Title: 2π1ν states populated in 135Te from 9Be-induced reactions with a 132Sn beam

Abstract

γ-ray transitions in 134Te, 135Te, and 136Te were measured from 9Be-induced reactions with a radioactive 132Sn beam at a sub-Coulomb barrier energy of 3 MeV per nucleon using particle-γ coincidence spectroscopy. The transitions were selected by gating on alpha-like particles in a CsI detector following a combination of (9Be,α1n), (9Be,α2n), and (9Be,α3n) incomplete fusion-evaporation reactions. Distorted-wave Born approximation calculations suggest little to no contribution from the (9Be,7He), (9Be,6He), and (9Be,5He) direct reactions.γ-ray transitions from previously known 2+Ⓧν2f7/2 and 4+Ⓧν2f7/2 multiplet members in 135Te are observed. A new γ ray is observed, assigned to the third-excited state in 135Te, and new 2+Ⓧν2f7/2 multiplet members are suggested. In addition, spin assignments are made by using recent one-neutron transfer data. The updated experimental data for 135Te are compared to shell-model calculations for a relatively complete set of states up to the yrast 15/2-,4+Ⓧν2f7/2 multiplet member at 1505 keV.
