Prompt {gamma}-ray cascades in neutron-rich nuclei around doubly magic {sup 132}Sn have been studied at Eurogam II using a {sup 248}Cm fission source. Here we report results for the four-valence-proton N=82 nucleus {sup 136}Xe and for its N=83 neighbor {sup 137}Xe. For both nuclei, the yrast level spectra have been considerably extended, and empirical nucleon-nucleon interactions have been used to assign probable shell model configurations. The {sup 136}Xe level energies are compared with those calculated using different sets of proton-proton interaction matrix elements, both diagonal and nondiagonal, obtained by fitting experimental data for other N=82 isotones. {copyright} {ital 1999} {ital The American Physical Society}
