Available in PDF, EPUB and Kindle. Book excerpt: Classical and quantal nonrelativistic scattering between simple atomic systems is reviewed, and most approximations currently used in calculations on electron capture are discussed. The OBK interaction is generalized to include capture from neutral atoms by singly charged many-electron ions; the sum over the squares of the vector coupling coefficients is affected in the formula for the OBK cross section for p-orbital capture by protons into H(ns). The cross section for H(+) + H(1s) to H(Sigma n1) + H(+) at high impact energies is determined classically. The second Born amplitudes at high impact energies for H(+) + H(1s) to H(1s) + H(+) and H(+) + D(1s) to H(1s) + D(+) are evaluated approximately using the Green's function of the post Hamiltonian. Two modifications of Thomas' classical model for heavy atoms are proposed, and corresponding cross sections are calculated for H(+) + B to H(Sigma n1) + B(+) with B = O, N, Ne, A, Kr, Xe. A semiclassical theory is developed for charge transfer in alkali atom-alkali-ion collision at low impact velocities, and cross sections are obtained for H, Li, Na, K, Rb, Cs. OBK cross sections are calculated for s-orbital capture from He(1s(2)), N((4)S), O((3)P), and p-orbital capture from N((4)S), O((3)P), all for incident protons capturing into H(1s). Born prior and post cross sections are calculated for H(+) + O((3)P) to H(1s) + O(+)((4)S) and H(1s) + H(1s) to H( - )(1s(2)) + H(+).

Book Synopsis The Physics of Multiply and Highly Charged Ions by : F.J. Currell
Download or read book The Physics of Multiply and Highly Charged Ions written by F.J. Currell and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly charged ions are the most chemically reactive species known to mankind. This reactivity is due to the extremely large potential energy they posses. This textbook deals with the wide range of interactions which occur when such ions interact with other forms of matter, especially solid surfaces and gasses. Particular emphasis is placed on situations where the kinetic energy associated with the interactions is small so that the effects of the high potential energy are most apparent. Experimental and theoretical techniques of investigation are covered in addition to the findings they produce. The treatment aims to be instructive to the beginner while leading on to a level where the newest findings are reviewed. As such the text is suitable for final year undergraduates, postgraduates or experienced researchers.

Available in PDF, EPUB and Kindle. Book excerpt: ''An atteJDpt has been made to cOll1PlJte the numbers of certain JI10lecules in interstellar space , . . . . A search for the bands of CH, O/{, DR, en and C2 would appear to be proIDising" P Swings and L Rosenfeld Astrophysical Journal 86,483(1937) This may have been the first attempt at modelling interstellar chemistry. As with models today, the methods used lacked reliability, but the speculation was impressive! Mark Twain might well have said of this infant subject "One gets such wholesale returns of conjecture out of such a trifling investment of fact". The detection of unidentified lines around the period that Swings and Rosenfeld were writing provoked much interest, but even the most optimistic speculator could hardly have imagined developments which would occur during the next 50 years. By 1987 about 70 varieties of molecule had been identified in the interstellar and circumstellar regions, They range in complexity from simple diatomics such as H2 and CO to such species as ethanol C2HeDH, acetone (CHs)2CO, and the largest interstellar molecule detected so far, cyano-penta acetylene HC11N, The study of these molecules in astronomy has developed enormously, especially over the last 20 years, and is now codified in the new subject of astrochemistry, That such a variety of chemical species should exist in tenuous regions of the Galaxy is fascinating.

Book Synopsis Particle Penetration and Radiation Effects Volume 2 by : Peter Sigmund
Download or read book Particle Penetration and Radiation Effects Volume 2 written by Peter Sigmund and published by Springer. This book was released on 2014-05-29 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents volume 2 of a 3-volume monograph on Particle Penetration and Radiation Effects. While volume 1 addressed the basic theory of scattering and stopping of swift point charges, i.e., protons, antiprotons and alpha particles, the present volume focuses on ions heavier than helium as well as molecules and clusters over an energy range from a few keV/u to a few hundred MeV/u. The book addresses the foundations in atomic-collision physics of a wide variety of application areas within materials and surface science and engineering, micro and nano science and technology, radiation medicine and biology as well as nuclear and particle physics. Problems have been added to all chapters. This should make the book useful for both self-study and advanced university courses. An effort has been made to establish a unified notation throughout the monograph.

This book was released on 2012-12-06 with total page 699 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early in 1989, while most of us were gathered in the Mediterranean five-centuries-old city of Alacant, the idea of a school on stopping and particle penetration phenomena came to our minds. Later that year when discussing this plan with some of the participants in the 13th International Conference on Atomic Collisions in Solids in Aarhus, we were pleased to note that the proposal was warmly welcomed indeed by the community. An Advanced Study Institute on this or a related subject had not been organized in the last decade. Because of the progress made particularly in the interaction of high energy beams with matter, and the many applications which the general subject of the stopping of charged particles (ions and electrons) in matter enjoys, a Study Institute appeared a worthy enterprise. Even though several international conference series cover developments in these areas, they miss tutorial introductions to the field. The title chosen was Interaction of Charged Particles with Solids and Surfaces, and the objectives were stated as follows: "to cover theory and experiments, including selected applications and hot topics, of the stopping of charged particles (ions and electrons) in matter. The emphasis will be on outlining the areas where further effort is needed, and on specifying the basic needs in applications. Fundamental concepts will prevail over applications, and the character of the Institute as a school will be stressed. " The school was directed by Fernando Flores (Spain), Herbert M. Urbassek (Germany), Nestor R.

This book was released on 2012-12-06 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the invited lectures and contributed papers presented at the V International Conference on the Physics of Highly Charged Ions, which was held at the lustus-Liebig-Universi tat Giessen, 10-14 September 1990. This conference was the ftfth in a series -after Stockholm (1982), Oxford (1984), Groningen (1986) and Grenoble (1988) -to deal with a rapidly growing fteld, which comprises the spectroscopy of highly charged ions and their interactions with photons, electrons, atoms, ions, and solids. Most of the matter of the universe is in the ionized state. Investigations dealing with hot plasmas on earth have been greatly furthered by thermonuclear-fusion research. The increasing maturity of this programme has revealed the fundamental role of highly charged ions in fusion plasmas. Today, it is clear that a detailed knowledge of the production mechanisms of highly charged ions and their interactions with other plasma constituents is an important prerequisite for a better understanding of the microscopic and macroscopic plasma properties. The study of highly charged ions involves various branches of physics. It was the aim of the conference to bring together physicists working in atomic collisions and spectroscopy, in plasma physics and astrophysics, as well as in solid-state and ion-source physics. About 220 scientists from 20 nations attended the conference, indicating the strong worldwide interest and the vital ity of research in this fteld.
