Abstract
The microscopic quasiparticle-phonon model, MQPM, is used to study the energy spectra of the odd Z=53 - 63, N=82 isotones. The results are compared with experimental data, with the extreme quasiparticle-phonon limit and with the results of an unrestricted 2s1d0g7/20h11/2 shell model (SM) calculation. The interaction used in these calculations is a realistic two-body G-matrix interaction derived from modern meson-exchange potential models for the nucleon-nucleon interaction. For the shell model all the two-body matrix elements are renormalized by the Q-box method whereas for the MQPM the effective interaction is defined by the G-matrix.
