Monopole effects and cross-shell excitations in particle-hole systems 134-136Xe
Monopole effects and cross-shell excitations in particle-hole systems 134-136Xe
摘要
The particle-hole nuclei 134-136Xe are studied using large-scale shell-model calculations with an extended pairing-plus-multipole interaction and monopole corrections.The negative-parity states 2-to 8-in 136Xe are predicted at 3.4-3.9 MeV.The quantitative analysis reveals that the monopole effects provide the dominant contribution to reproducing the spectroscopic structure of 135Xe.The monopole effects between the πg7/2 and νh11/2 orbits substantially improve the shell-model precision in these particle-hole nuclei 134-136Xe near the doubly magic nucleus 132Sn.
