Atlas of Neutron Resonances: Resonance Properties and Thermal Cross Sections Z=1-102, Sixth Edition, features an extensive list of detailed individual neutron resonance parameters, thermal cross sections, average resonance parameters and a short survey of the physics of thermal and resonance neutrons. The long introduction contains: nuclear physics formulas aimed at neutron physicists; topics of special interest such as valence neutron capture, nuclear level density parameters, sub-threshold fission and electric dipole radiation treated; and various comparisons of measured quantities with the predictions of nuclear models, such as the optical model and the generalized Landau-Fermi liquid mode.
As in the last edition, additional features have been added to appeal to a wider spectrum of users. These include: spin-dependent scattering lengths that are of interest to solid-state physicists, nuclear physicists, and neutron evaluators; calculated and measured Maxwellian average 5-kev and 30-keV capture cross sections of importance to astrophysicists involved in nucleosynthesis modeling; s-, p-, and d- wave average radiative widths; and nuclear level density parameters. The various evaluated neutron strength functions, as well as the scattering radii, are compared with optical model predictions. Extensive applications of the Porter-Thomas distribution, coupled with Bayesian analysis, was made to determine the parity and spacings of neutron resonances.
