Abstract:We studed alpha decay half-lives of Pb isotopes in the range 178 ≤ A ≥ 220, whithin Gamow-like model (GLM) which is based on Gamow theory. The empirical formulae like Royer formula, Universal Decay Low (UDL), Viola-Seaborg formula (VSS), Semi-empirical formula for Poenaru (SemFIS) and Denisov & Khudenko formula (DEKH) are used to calculate alpha decay half-lives. The results are compared with experimental data, and also with other theoretical models, the results are in a good agreement was achieved with experimental data.

“…α decay, as an important tool to investigate SHN, provides abundant information about the nuclear structure and stability of SHN [6,12,1,13]. Nowadays, there are many theoretical models used to study α decay including the cluster model [14,15,16], the unified model for α decay and α capture [17,18], the liquid drop model [19,20,21,22,23], the two-potential approach [24,25,26,27,28,29,30], the empirical formulas [1,31,32,33] and others [34,35,36,37,38,39].…”

Systematic study of α decay half-lives based on Gamow–like model with a screened electrostatic barrier

et al. 2019

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.

“…Also the half-life for the emission of various clusters from even-even isotopes of barium in the ground and excited states were studied using the Coulomb and proximity potential model by Santhosh et al [28]. Also, there are many efficient and useful empirical formulas to calculate alpha decay half-lives which are given in reference [29][30][31][32]. In this study we used three different nuclear potential including Coulomb proximity potential (CPPM), Royer proximity potential (RPP) and Broglia and Winther 1991 model (BW91).…”
