Decay Properties Of The Dipole Isobaric Analog Resonances

Abstract

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
