Calculations of the α -decay half-lives of 166 190 Pt  isotopes have been carried out using the modified Gamow-like model (MGLM) and deformed Woods-Saxon potential model. In order to see the effect of using deformed nuclear potential on the α -decay half-lives of the Platinum isotopes, the spherical Woods-Saxon potential has also been employed in the computation. When compared with experimental data, all the models give very good descriptions of the experimental half-lives. The comparison also suggests that the calculated half-lives considering deformation give better agreement with the experimental data than the results using spherical configuration. New parameter values were obtained for the MGLM model (termed MGLM2). The MGLM2 model gives better descriptions of the half-lives than the MGLM1 model.

“…The mechanism of α-decay is a widely studied topic. In order to understand the α-decay, realistic nuclear potentials are proposed in many studies and the experimental data were compared [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

In this paper, we investigate the role of potential deformation in explaining the α-decay. The deformation of the nuclear potential has been taken into account by adding a Gaussian potential to the well-known Wood-Saxon potential. For the numerical calculations, the Wentzel-Kramers-Brillouin method has been used, and also the Bohr-Sommerfeld quantization condition has been employed to restrict the parameters. The half-lives of ten nuclei have been calculated for α-decay and very good agreement has been obtained with the experimental data.

“…The study of proton emission can extract meaningful information about the nuclear structure beyond the proton drip line, e.g., the shell structure and the coupling between unbound and bound nuclear states [2]. Currently, many models have been used to study α decay, such as the unified model for α decay and α capture [3,4], the empirical formulas [5][6][7][8][9][10][11], the twopotential approach [12,13], the cluster model [14][15][16], the liquid drop model [17][18][19][20][21], the generalized liquid drop model [22,23] and others [24][25][26][27][28][29][30][31][32]. There are also many theoretical models used to study proton emission or the different forms of interactions used to construct these models, such as the single-folding model [33,34], the Coulomb and proximity potential model (CPPM) [35], the distorted-wave Born approximation [36], the R-matrix approach [37], the coupled-channel approach [38][39][40], the relativistic density functional theory [41], the generalized liquid drop model [42][43]…”

In the present work, α decay and proton emission half-lives are studied by the deformed Gamow-like model, which introduces the effects of the nucleus' deformation. The calculations show that it is necessary to consider the deformation in the calculation for nuclei far from the shell. Moreover, this model is used to predict the proton emission half-lives of the nuclei far from the shell more accurately. The calculations indicate that our deformed model follows the Geiger-Nuttall law. Furthermore, the deformed Gamow-like model is used to study the shell structure, and we find that the number of the next neutron shell is likely to be 152. This work may benefit future research on the search for superheavy nuclei and new proton radionuclides.
