Özet: Neutral tellurium detected in three metal-poor stars enriched by products of r-process nucleosynthesis by using near-ultraviolet spectra obtained with the Space Telescope Imaging Spectrograph on board the Hubble Space Telescope. Tellurium (Te, Z=52) was found at the second r-process peak (A≈130) associated with N=82 neutron shell closure. The beta decay rates of unstable isotopes may be drastically changed under stellar conditions. In this work, we have been investigated the first forbidden (|∆J|=0, 1 and 2) transitions strength of some neutron rich Tellurium isotopes. The theoretical framework is based on a proton neutron quasiparticle random phase approximation (pn-QRPA) in the particle-hole (ph) channel. The transition probabilities in the Woods-Saxon potential basis have been calculated within the x-approximation. The calculated first forbidden b-decay logft values are in better agreement with experimental data.
