Abstract

Unified nuclear potential originates from the modified liquid drop model by taking the double volume integral of the Yukawa folding function and incorporating the surface diffuseness parameter. The present study aims to measure the half-lives of two-proton (2p) emission from experimentally identified two-proton emitters. Further, its dependence on the spectroscopic factor has been studied. At first, for the experimentally identified 2p emitters, systematic calculations by varying the factor \(\chi \) between 0.0001 and 1, half-lives are calculated. The results show, best matching between the experimental and calculated half-lives. Also the study confirmed the cubic polynomial relation between the spectroscopic factor and the factor \([A/(A-2)]^{Z/2}\). Half-lives calculated using this relation are found to match well with experimental ones. In addition to this, branching ratio is calculated between 2p emission with respect to one-proton (1p) emission for those experimentally identified 2p emitter nuclei with positive Q\(_{1p}\) values. This confirmed true two-proton emission of these nuclei. Further the study has been extended to analyze the theoretically predicted 2p emitters and their 1p emission. Half-lives better match with other theoretical predictions and branching ratio are calculated to find preference of 2p emission over 1p emission.
