Two-proton radioactivity within a generalized liquid drop model
PHYSICAL REVIEW C(2020)
摘要
The generalized liquid drop model (GLDM) is first extended to study the two-proton (2p) radioactivity half-lives of the ground state of nuclei. According to the comparison between the calculated half-lives and the experimental data, it is shown that the GLDM describes the 2p radioactivity half-lives well. In addition, by comparing its accuracy with other models, it is found that the GLDM has a comparable accuracy with them. Finally, the 2p radioactivity half-lives of some of the most probable candidates are predicted with the GLDM by inputting the Q(2p )values (the released energy of the 2p radioactivity) from the updated 2016 Atomic Mass Evaluation mass table, which may be useful for future experiments.
