摘要

Abstract

In the present work, we extend the Coulomb and Proximity Potential Model (CPPM) to study two-proton (2p) radioactivity from excited states while the proximity potential is chosen as AW95 proposed by Aage Withner in 1995. Demonstration reveals that the theoretical results acquired by CPPM exhibit a high level of consistency with prior theoretical models, such as the unified fission model (UFM), generalized liquid drop model (GLDM) and effective liquid drop model (ELDM). Furthermore, within the CPPM, we predicted the half-lives of potential 2p radioactive nuclei for which experimental data are currently unavailable. The predicted results were then assessed, compared with UFM, ELDM, and GLDM models, and examined in detail.
