Two-proton radioactivity from excited states of proton-rich nuclei within Coulomb and Proximity Potential Model

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.

Zusammenfassung: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.
