This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Spontaneous fission provides a very natural production mechanism for neutron-rich nuclei. The large excesses of neutrons over protons in heavy systems near the valley of stability, coupled with the tendency for the charge-to-mass ratio to be preserved in the fission process, results in fission fragments that lie well to the neutron-rich side of stability. The excitation energy of the primary fragments produced at scission results in the evaporation of neutrons (Fig 1) to produce secondary fragments whose excitation energy is dissipated through[gamma]-ray emission. In the last few years the study of such[gamma] rays has produced a dramatic increase in the available information on the structure of neutron-rich nuclei. This renaissance in fission-fragment spectroscopy has been due primarily to the much increased resolving power of large arrays of germanium[gamma]-ray detectors such as Euroball and Gammasphere. Through the improved detection efficiency and high granularity, these arrays have made it possible to obtain reasonable rates for the detection of three coincident[gamma] rays out of the cascades of multiplicity ten that are typically produced in spontaneous fission. In addition to the determination of the energies of excited levels, developments in spectroscopic techniques have allowed for information to be deduced regarding the spins and parities[1,2] and lifetimes[3,4] of such states of extreme isospin. In this paper we present research that has been carried out using the Euroball and Eurogam arrays to detect[gamma] rays emitted from spontaneously fissioning[sup 248]Cm and[sup 252]Cf. The paper focuses on three sub-areas of current activity, namely, the measurement of yields of secondary fragment pairs, the measurement of state lifetimes at around spin 10, and recent measurements of g-factors of excited states in fission fragments.

Download or read book Shape and Structure of Neutron-rich Nuclei from 252Cf Fission Fragments written by Jason Benjamin Snyder and published by . This book was released on 2014 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transition quadrupole moments, Qt, of rotational bands in the neutron-rich, even-mass 102-108Mo and 108-112Ru nuclei were measured with the Doppler-shift attenuation method. The nuclei were populated as fission fragments from 252Cf fission. The detector setup consisted of the Gammasphere spectrometer and the Hercules fast-plastic array. This allowed the measurement of asymmetric DSAM lineshapes at different Gammasphere detector angles with respect to the fission axis. The measurements typically covered the 6 to 16h spin range of the ground-state band and at least a strong transition in the [gamma] band. At moderate spin, the Qt moments are found to be reduced with respect to the values near the ground states, the latter being reported in the literature. An attempt has been made (by Afanasjev) to describe the data in the framework of cranked relativistic Hartree-Bogolyubov theory, and the results are reported in the present work as well as in a Physics Letters paper by Snyder et al. For 104Mo reliable predictions can be made. Here an oblate shape and a low-spin triaxial shape (deformation parameter [gamma]~-44°), predicted to be favored in other theoretical calculations, are ruled out by the data. There is some indication for a gradual change, at higher spin, from an initially prolate shape to a triaxial shape in 104Mo. The Qt data for 106Mo and 110,112Ru support this picture. The challenge of theory to describe the Qt data is addressed, which has to do with the very [gamma]-soft potential-energy surfaces. As a byproduct of the Qt analysis (which requires the determination of the intensities of the feeding transitions), the transition intensities of many weak high-spin or non-yrast states have been determined. These previously unknown intensity data are also reported. In the appendix, the results of an attenuation-coefficient analysis for [gamma]-ray angular distributions (due to recoil-in-vacuum) in heavy Ba isotopes are reported. These results are from a separate project, though from the same data set.

Available in PDF, EPUB and Kindle. Book excerpt: One fragment-[gamma]-[gamma] and three [gamma]-[gamma] coincidence measurements of the prompt [gamma]-rays from the fragments produced in the spontaneous fission (SF) of 252Cf and very recently of 242Pu were carried out with a 20 Ge detector ball at HHIRF. With our high statistics, [gamma]-[gamma]-[gamma] coincidences where the two gates are on transitions in the two partner fragments were extracted. Comparing the 252Cf and 242Pu data allowed unique placements of many transitions. New, higher spin states were observed in many nuclei, up to 16 in some of the heavy partners. Levels in several nuclei were observed for the full time. Studies of the fission process included measured relative branchings to the 1n to 6n channels. Much data remains to be analyzed. These data provide new insights into the changing structures at higher spins of many neutron-rich nuclei and the fission process.

Available in PDF, EPUB and Kindle. Book excerpt: Decay spectroscopy of neutron rich nuclei near doubly magic 78Ni [78-Nickel] is relevant to nuclear structure and astrophysics as well as reactor and neutrino physics. [upper case beta]-decay [betadecay] calorimetry studies are essential to reconstruct the decay strength function and is used to overcome the problems arising from the high density of states leading to nuclear Pandemonium. The Modular Total Absorption Spectrometer, currently located in HRIBF at the Oak Ridge National Laboratory, collected data on 25 fission products of 238U [238- Uranium] during a run in March 2015. Analysis of the 84,̳85,̳86Br [84, 85 and 86-Bromine] data from the March 2015 run indicates a significant modification of the [upper case beta]-strength [betastrength] function when compared with previous measurements for all three nuclei, including the introduction of new high energy states not previously detected. The cases of 84,̳85,̳86Br will be discussed in concert with shell model predictions. 85Br [85-Bromine] is a singly magic N=50 nucleus. Through the study of N=49,50,51 nuclei the decay properties around a neutron shell closure governed by the interplay between core and valence nucleon excitations and Gamow-Teller decay in a 78Ni [78-Nickel] core can be understood and provide a pinpoint for the study of more exotic nuclei.
