Tellurium (Te, Z=52) wasfound at the second r-process peak (A?130) associated with N=82 neutron shellclosure. The beta decay rates of unstable isotopes may be drasticallychanged under stellar conditions. In this work, we have been investigated thefirst forbidden (|?J|=0, 1 and 2) transitions strength of some neutron richTellurium isotopes. The theoretical framework is based on a proton neutronquasiparticle random phase approximation (pn-QRPA) in the particle-hole (ph)channel. The transition probabilities in the Woods-Saxon potential basis havebeen calculated within the x-approximation.The calculated first forbidden b-decay logft valuesare in better agreement with experimental data.eninfo:eu-repo/semantics/openAccessFirst Forbidden?-DecayLogftFirst Forbidden?-DecayLogftArticle1NSP2018 Özel Sayı4551
