Download or read book Elastic Scattering of Low-energy Electrons from Oxygen written by William Lewis Johnson and published by . This book was released on 1966 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cross sections for the elastic scattering of electrons from atomic oxygen are calculated in the energy range between 0 and 13.6 electron volts. Polarization of the atom is included by using a term in the potential function which has the correct asymptotic behavior and which vanishes at the origin. Previous theoretical and experimental results are discussed.

Download or read book The Effect of Several Configuration Interaction Target States on the Elastic Scattering of Low-energy Electrons by Complex Atoms written by Ed R. Smith and published by . This book was released on 1975 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total wave function (target plus incident electron) is represented by a close coupling expansion. For complex atoms such as atomaic helium and oxygen, the effects of configuration interaction target states are discussed and analyzed, in part. For atomic helium, the doublet S partial-wave elastic cross section obtained using a He configuration interaction ground state is virtually identical with the corresponding cross section obtained using a Roothaan-Hartree-Fock ground state. In all cases studied, the elastic phase shift is shown to increase with the addition of atomic states and explicit correlation states into the expansion for the total wave function. For atomic oxygen, the quartet P partial-wave elastic phase shift can increase to such an extent as to introduce a 'resonance' behavior into the low-energy part of the elastic cross section. Finally, a second procedure is discussed for including correlation states when CI target states are used in the close-coupling expansion.

Download or read book Low-energy Electron Scattering from Atoms and Molecules: a Model written by Carl J. Lenander and published by . This book was released on 1966 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple model is proposed for the calculation of free-electron wave functions for low-energy electrons incident upon neutral atoms. The region of interaction of the electron with the atom may be separated into three regions, according to the importance of potential: Coulomb plus exchange; Coulomb; and far-field induced polarization. The division of regions is based on mathematical and physical reasons for the characteristic behavior of wave functions in the scattering problem. Examples are given for the elastic scattering of electrons from nitrogen, oxygen and argon. The agreement with experiment and effective-range theory is good. The application of the method to prediction of low-energy electron scattering from homonuclear diatomic molecules is discussed. (Author).

Book Synopsis Low-energy Electron Scattering from Atomic Oxygen by : R. H. NEYNABER
Download or read book Low-energy Electron Scattering from Atomic Oxygen written by R. H. NEYNABER and published by . This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total cross section for the scattering of electrons by atomic O was measured as a function of electron energy from 2.3 to 11.6 ev. The number of electrons scattered from a region defined by the intersection of an electron beam and a modulated molecular O beam was compared with the number scattered when the O beam was partially dissociated. A radio-frequency discharge dissociated about 30% of the molecules. The degree of dissociation was measured with a mass spectrometer. From the data, the ratios of atomic to molecular scattering cross sections were obtained. The absolute atomic values were calculated by multiplying these ratios by the molecular O cross sections obtained by Bruche (Ann. Physik 83:1065, 1957). The result is a virtually constant cross section of 6.2! 0.5 a2o in the entire energy range studied. These results are compared with 5 theoretical estimates. (Author).

Download or read book Elastic Scattering of Low-energy Electrons by Randomly Oriented and Aligned Molecules written by and published by . This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Elastic scattering of low (10-50 eV) kinetic energy electrons from free diatomic molecules is studied using a single-center expansion of the full molecular potential. Dynamic exchange and polarization are included in a local form. The calculated elastic differential scattering cross-sections (DCS) for electron impact on CO and N2 are in good agreement with available experimental data. The importance of using the full molecular potential instead of a two-center potential approach is pointed out. These corrections are small for energies above 50 eV, but they become increasingly important at lower energies. When discussing the angular distributions of elastically-scattered electrons from oriented molecules (like surface adsorbates), we show that these corrections are particularly significant. The results have implications for other electron scattering problems such as those encountered in low-energy photoelectron diffraction from both core and valence levels.
