摘要

Abstract

In this study, we systematically investigated the two-proton (2p) radioactivity half-lives from the excited state of nuclei near the proton drip line within the Gamow-like model (GLM) and modified Gamow-like model (MGLM). The calculated results were highly consistent with the theoretical values obtained using the unified fission model [Chin. Phys. C 45, 124105 (2021)], effective liquid drop model, and generalized liquid drop model [Acta Phys. Sin 71, 062301 (2022)],. Furthermore, utilizing the GLM and MGLM, we predicted the 2p radioactivity half-lives from the excited state for some nuclei that are not yet available experimentally. Simultaneously, by analyzing the calculated results from these theoretical models, it was found that the half-lives are strongly dependent on ,Q,2p, and , $l$ ,.
