“…In our previous works [29][30][31][32], we chose nuclear potential V N (r ) as a type of cosh parameterized form proposed by Buck et al [27] to systematically study the α decay halflives of even-even, odd-odd and odd-A nuclei. In this work, we generalize this cosh type nuclear potential to study proton radioactivity.…”

“…While the nuclear potential of the emitted α-daughter nucleus is adopted by a parameterized cosh type. In our previous works [29][30][31][32], we used the two-potential approach (TPA) [33] with cosh type potential to systematically study α decay half-lives and the calculations can reproduce the experimental data well. Zhang et al [34] improved the cluster model with cosh type potential to explain the proton radioactivity and proposed a phenomenological formula to calculate the half-life of this process.…”

In the present work we systematically study the half-lives of proton radioactivity for spherical proton emitters with Z ≥ 69 based on two-potential approach. While the nuclear potential of the emitted proton-daughter nucleus is adopted by a parameterized cosh type, the parameters of the depth and diffuseness for nuclear potential are determined by fitting experimental data of 32 spherical proton emitters. In order to reduce the deviations between experimental half-lives and calculated ones, we propose a simple analytic expression for formation probability of proton radioactivity with the same orbital angular momentum l. The results indicate that the formation probability can be simply described by a formula of A 1/3 d . Moreover, the linear relationship between the formation probability and the fragmentation potential also exists. The calculated half-lives can well reproduce the experimental data. 0123456789().: V,-vol

In the present work we systematically study α decay half-lives of Z > 51 nuclei using the modified Gamow-like model which includes the effects of the centrifugal potential and electrostatic shielding. For the case of even-even nuclei, this model contains two adjustable parameters: the parameter a related to the screened electrostatic barrier and the radius constant r 0 , while for the case of odd-odd and odd-A nuclei, it is added a new parameter i.e. hindrance factor h which is used to describe the effect of an odd-proton and/or an odd-neutron.Our calculations can well reproduce the experimental data. In addition, we use this modified Gamow-like model to predict the α-decay half-lives of seven even-even nuclei with Z = 120 and some un-synthesized nuclei on their α decay chains.

In the present work we systematically study the half-lives of proton radioactivity for spherical proton emitters with Z ≥ 69 based on two-potential approach. While the nuclear potential of the emitted protondaughter nucleus is adopted by a parameterized cosh type, the parameters of the depth and diffuseness for nuclear potential are determined by fitting experimental data of 32 spherical proton emitters. In order to reduce the deviations between experimental half-lives and calculated ones, we propose a simple analytic expression for formation probability of proton radioactivity with the same orbital angular momentum l. The results indicate that the formation probability can be simply described by a formula of A 1/3 d . Moreover, the linear relationship between the formation probability and the fragmentation potential also exists. The calculated half-lives can well reproduce the experimental data.
