On the role of anti-bound states in the RPA description of the giant monopole resonance
Tóm tắt
The limit of the applicability of the resonant random phase approximation method is tested by calculating escape widths in the giant monopole resonance of16O and comparing them to the results of a time dependent Hartree-Fock calculation. Though the widths of the narrows-wave component agree reasonably well, the broadp-wave component shows large disagreement, which cannot be cured by complementing the basis with anti-bound states in the RPA calculation.
