Shell-model description of the nucleusTe132

Microscopic proton two-particle neutron two-hole shell-model calculations have been performed for the nucleus ${}_{52}{}^{132}{}_{}{}^{}\mathrm{Te}_{80}^{}{}_{}{}^{}$. Evidence results for the existence of a weak-coupling pattern obtained by coupling nuclear low-lying levels in ${}_{52}{}^{134}{}_{}{}^{}\mathrm{Te}_{82}^{}{}_{}{}^{}$ and ${}_{50}{}^{130}{}_{}{}^{}\mathrm{Sn}_{80}^{}{}_{}{}^{}$. Electromagnetic properties for the most important low-lying levels in ${}_{52}{}^{132}{}_{}{}^{}\mathrm{Te}_{80}^{}{}_{}{}^{}$ are also calculated and compared with existing experimental data. The limitations of proton two-particle- (neutron two-hole-) core coupling calculations are also exhibited when proton and/or neutron number only deviates from closed shell configurations by a small (±2) number.
