PROTON RADIOACTIVITY OF TANTALUM

Abstract

Using different models such as Coulomb and proximity potential model, effective liquid drop model and modified generalised liquid drop model, we have studied all possible one proton radioactivity tantalum. The calculated half-lives from the present work are compared with the available experiments. One proton decay energy is studied using recent mass excess values [Chinese Physics C Vol. 45, No. 3 (2021) 030003]. The angular momentum dependence of potential have been considered. The penetration probability ( P ) is studied using WKB integral. The decay constant ( ) and halflives ( 1/ 2 T ) of 151-157Ta were predicted. The identified one proton radioactivity of 151-157Ta along with half-lives and decay energies plays an important role in the future experiments. Present work may find useful applications in radiotherapy and diagnosis.
