Abstract: High-spin states in Te132, an isotope with two proton particles and two neutron holes outside of the Sn132 doubly magic core, have been extended up to an excitation energy of 6.17 MeV. The prompt-delayed coincidence technique has been used to correlate states above the T1/2=3.70(9)μs isomer in Te132 to the lower states using Th232(Li7,f) at 5.4 MeV/u and the Indian National Gamma Array (INGA). With Be9(U238,f) at 6.2 MeV/u and EXOGAM γ-array coupled with the VAMOS++ spectrometer, the level scheme was extended to higher excitation energies. The high-spin positive-parity states, above Jπ=10+, in Te132 are expected to arise from the alignment of the particles in the high-j orbitals lying close to the Fermi surface, the πg7/22, and the νh11/2-2 configurations. The experimental level scheme has been compared with the large scale shell model calculations. A reduction in the p-n interaction strength resulted in an improved agreement with the measurements up to the spin of 15. In contrast, the comparison of the differences between the experiment and these calculations for the N=76,78 isotones of Te and Sn shows the increasing disagreement as a function of spin, where the magnitude is larger in Te than in Sn. This behavior could possibly be attributed to the deficiencies in the p-n correlations, in addition to the n-n correlations in Sn. © 2016 American Physical Society.
