@article{Samanta2007PredictionsOA, title={Predictions of alpha decay half lives of heavy and superheavy elements}, author={C. Samanta and P. Chowdhury and D. N. Basu}, journal={Nuclear Physics}, year={2007}, volume={789}, pages={142-154} }

Abstract Theoretical estimates for the lifetimes of several isotopes of heavy elements with Z = 102 – 120 are presented by calculating the quantum mechanical tunneling probability in a WKB framework and using microscopic nucleus–nucleus potential obtained by folding the densities of interacting nuclei with the DDM3Y effective nuclear interaction. The α -decay half lives calculated in this formalism using the experimental Q -values are in good agreement over a wide range of experimental data… Expand
