Decay Properties Of The Dipole Isobaric Analog Resonances
A continuum-RPA-based approach is applied to describe the decay properties of
isolated dipole isobaric analog resonances in nuclei having not-too-large
neutron excess. Calculated for a few resonances in 90Zr the elastic
E1-radiative width and partial proton widths for decay into one-hole states of
89Y are compared with available experimental data.Comment: 8 pages, 4 figures, prepared with RevTe
Evaluation of the mean intensity of the P-odd mixing of nuclear compound states
A temperature version of the shell-optical-model approach for describing the
low-energy compound-to-compound transitions induced by external single-particle
fields is given. The approach is applied to evaluate the mean intensity of the
P-odd mixing of nuclear compound states. Unified description for the mixing and
electromagnetic transitions allows one to evaluate the mean intensity without
the use of free parameters. The valence-mechanism contribution to the mentioned
intensity is also evaluated. Calculation results are compared with the data
deduced from cross sections of relevant neutron-induced reactions.Comment: LaTeX, 10 page
