“…Our calculated results indicated that for the nuclei having the larger proton number , the experimental data can be better reproduced. Recently, W A Yahya computed the α decay half-lives for 171−189 Hg isotopes using the Gamow-like model, modified Gamow-like model, temperature-independent Coulomb and proximity potential model and temperature-dependent Coulomb and proximity potential model, it is found that the calculated α decay half-lives obtained by using the modified Gamow-like model, temperature-independent Coulomb and proximity potential model are in better agreement with the experimental data [66].…”

In this study, taking into account of the contribution of the centrifugal potential on half-life and the effect of electrostatic shielding, we modify the Gamow-like model proposed by Zdeb et al. [Phys. Rev. C 87, 024308 (2013)] to systematically investigate the cluster radioactivity half-lives of nuclei ranging from 221Fr to 238U. The calculated results can reproduce the experimental data well. Additionally, this modified Gamow-like model is applied to predict the half-lives of cluster radioactivity nuclei whose experimental half-lives have the lower limit. It is found that the predicted results are in good agreement with the ones obtained by using the Gamow-like model and a Viola-Seaborg type formula.

“…The Gamow theory explained that the α-decay was as a result of the quantum mechanical tunnelling of a charged α particle through the nuclear Coulomb barrier [4]. Since then, many theoretical models and empirical formulas have been employed in the investigation of α-decay half lives of nuclei [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Some of the successful empirical formulas in the calculations of α-decay half-lives include Viola and Seaborg formula (VSS) [20], Brown formula [21], Royer formula [22,23], Poenaru formula [24], Wang formula [25], Denisov-Khudenko (DK) formula [26], AKRE formula [27], Ren et al formulas [28], New Ren et al formulas [29], etc.…”

“…The use of the Hulthen type of screened electrostatic potential in nuclear decay was first introduced in [38] to study proton radioactivity. Following its success, the Hulthen potential was employed in the modified Gamowlike model to study α-decay by Cheng et al [5] and later by [6]. The α-daughter nucleus potential in the modified Gamow-like model (MGLM) includes the Hulthen type of screened electrostatic Coulomb potential and the centrifugal potential.…”

α-decay half-lives of superheavy nuclei have been studied using modified Gamow-like model and improved empirical formulas. The empirical formulas used in the study are Viola-Seaborg semi-empirical formula, universal decay law (UDL), Denisov-Khudenko formula (DK), Royer formula, Wang formula, AKRE formula, and new Ren B (NRB) formula. New values of the adjustable parameters in the modified Gamow-like model have been obtained using a least square fit scheme and input data from the NUBASE2020 database. We found that only two adjustable parameters are sufficient to describe the α-decay half-lives of heavy and superheavy nuclei. We also obtained new coefficients for the seven empirical formulas using similar procedure. The modified Gamow-like model (MGLM) and improved empirical formulas are then used to calculate the α-decay half-lives of measured superheavy nuclei with Z = 100 − 118. The calculated root mean square errors indicate that the Royer, DK, and AKRE formulas are the best three empirical formulas for evaluating the α-decay half-lives of the superheavy nuclei. The five best performing empirical formulas, together with the MGLM, are then used to predict alpha-decay half-lives of unmeasured even-even superheavy nuclei with Z = 120 − 126. The Q α values used for the predictions have been taken from the tabulated Weizsäcker-Skyrme-4+RBF (WS4+RBF) Qα values. The theoretical calculations suggest that N = 184 is a possible magic number, which is in agreement with previous theoretical calculations.

Elastic scattering cross sections are a fundamental aspect of nuclear physics research, and studying the cross sections of various nuclei can provide important insights into the behavior of nuclei. In this study, the elastic scattering cross sections of 10C projectile by 27Al, 58Ni, and 208Pb target nuclei are analyzed. The aim of this study is to investigate the cluster structure of 10C and the sensitivity of the elastic scattering cross sections to different potentials. To achieve this objective, the double folding optical model and a simple cluster approach are used to analyze the cross sections. The real part of the optical potential is obtained by folding two different effective interactions, Michigan-3-Yukawa (M3Y) and JeukenneLejeune-Mahaux (JLM), with four different cluster density distributions of the 10C nucleus: 6Be + \alpha, 9B + p, 8Be + p + p, and \alpha + \alpha + p + p. The imaginary part is taken to be a Woods-Saxon phenomenological form. The sensitivity of the elastic scattering cross sections to different potentials is assessed by comparing the results obtained using different potentials. The cluster structure of 10C is validated by comparing the theoretical results with experimental data. The results show that the cross sections are sensitive to the choice of potential used and that the cluster structure of 10C is validated. The theoretical results show reasonable agreement with the experimental data.
