Title: 2p1v states populated in 135Te from 9Be induced reactions with a 132Sn beam

Gamma-ray transitions in $$^{134}$$\textrm{Te}, $$^{135}$$\textrm{Te}, and $$^{136}$$\textrm{Te} were measured from $$^{9}$$\textrm{Be} induced reactions with a radioactive $$^{132}$$\textrm{Sn} beam at a sub-Coulomb barrier energy of $3$~MeV per nucleon using particle-$$\gamma$$ coincidence spectroscopy. The transitions were selected by gating on alpha-like particles in a \textrm{CsI} detector following a combination of ($$^{9}$$\textrm{Be},$$\alpha 1n$$), ($$^{9}$$\textrm{Be},$$\alpha 2n$$), and ($$^{9}$$\textrm{Be},$$\alpha 3n$$) reactions. Distorted wave Born approximation calculations suggest little to no contribution from the ($$^{9}$$\textrm{Be},$$^{7}$$\textrm{He}), ($$^{9}$$\textrm{Be},$$^{6}$$\textrm{He}), and ($$^{9}$$\textrm{Be},$$^{5}$$\textrm{He}) direct reactions. Gamma-ray transitions from previously known $$2^+\otimes \nu\, 2f_{7/2}$$ and $$4^+\otimes \nu\, 2f_{7/2}$$ multiplet members in $$^{135}$$\textrm{Te} are observed. A new $$\gamma$$-ray is observed, assigned to the third excited state in $$^{135}$$\textrm{Te}, and new $$2^+\otimes \nu\, 2f_{7/2}$$ multiplet members are suggested. In addition, spin assignments are made using recent one-neutron transfer data. The updated experimental data for $$^{135}$$\textrm{Te} are compared to shell-model calculations for a relatively complete set of states up to the yrast $$15/2^-, 4^+\otimes \nu\, 2f_{7/2}$$ multiplet member at 1505 keV.
