| 摘 要： | 通过引入离心势和静电屏蔽效应对Gamow-like模型进行了改进，并将其用于α衰变和质子放射性研究，发现改进的Gamow-like模型能更好地符合实验数据。另外，还利用改进的Gamow-like模型预言了16个丰质子核的质子放射性的半衰期以及7个$Z=120$超重核素($^{296-308}120$)α衰变链上原子核的α衰变的半衰期，为将来在大科学装置上合成和鉴别这些新核素提供重要的理论参考。

| Abstract: | In this paper, the Gamow-like model is improved by introducing centrifugal potential and electrostatic shielding, and it is used in the study of α decay and proton radioactivity. It is found that our calculations can well reproduce the experimental data. In addition, the modified Gamow-like model is used to predict the proton radioactivity half-lives of 116 proton-rich nuclei and α decay half-lives of seven even-even nuclei with $Z=120$($^{296-308}120$) and some nuclei on their α decay chains. It will provide important theoretical references for the synthesis and identification of these new nuclides on large scientific devices in the future. |
