Improved Description of the Fragmentation of Nuclear Collective States

摘要

A mathematical method is deveioped for a more accurate description of the fragmentation of one-phonon states forming giant resonances. The method consists in that the one-phonon states already fragmented are used in the two-phonon terms of wave functions. Strength functions are obtained for the excitation of collective charge-exchange states and giant resonances in spherical nuclei. (Atomindex citation 16:056500)
