Abstract
Excited levels of Te130 were studied with the (n, n'?) reaction. Excitation functions, coincidences, angular distributions, and Doppler shifts were measured for ? rays from levels up to an excitation energy of 3.3 MeV. Detailed information that includes level lifetimes, multipole-mixing ratios, branching ratios, and electromagnetic transition rates deduced from these measurements is presented. Large-scale shell model calculations performed with all proton and neutron orbitals in the 50-82 shell are compared to these data, with generally good agreement, particularly for the positive-parity states. To investigate emerging collectivity in Te130, the Kumar-Cline sum rules were used to evaluate rotational invariants from the shell model calculations. Whereas the ground state and first-excited state show the greatest average deformation, as expected, all of the low-lying states are weakly deformed and triaxial.
