Nuclear structure studies with pick-up reactions on even tellurium nuclei: The 120Te(d,t)119Te and the 120Te(τ,α)119Te reactions

The level structure of 119Te has been investigated up to an excitation energy of ≅ 1.2 MeV by the (d,t) reaction and up to ≅ 2.3 MeV by the (τ,α) reaction using beams of 17 MeV deuterons and 24 MeV τ-particles. Angular distributions were recorded and analyzed with standard DWBA calculations. Spectroscopic factors were deduced. Anomalous angular distributions and cross sections of some low-lying and weakly excited states were explained using CCBA calculations. A previously known isomeric 11-/2 state has been found to have an excitation energy of 262 keV. (orig.)
