High-lying Gamow-Teller states in the spherical nuclei
Description
It was shown by calculation in the Random Phase Approximation that non-local separable residual interactions can form the additional collective Gamow-Teller (GT) states placed considerably higher than the usual giant GT resonance. These states can absorb the considerable part of the strength of the σt(-) transitions. The distribution of the GT transition strength over excitation energy in the giant resonance region and in the low energy region corresponds to the known experimental data. (author). 11 refs., 2 figs
