# Search for long lived heaviest nuclei beyond the valley of stability

@article{Chowdhury2008SearchFL, title={Search for long lived heaviest nuclei beyond the valley of stability}, author={P. Chowdhury and C. Samanta and D. N. Basu}, journal={Physical Review C}, year={2008}, volume={77}, pages={044603} }

The existence of long lived superheavy nuclei (SHN) is controlled mainly by spontaneous fission and {alpha}-decay processes. According to microscopic nuclear theory, spherical shell effects at Z=114, 120, 126 and N=184 provide the extra stability to such SHN to have long enough lifetime to be observed. To investigate whether the so-called 'stability island' could really exist around the above Z, N values, the {alpha}-decay half-lives along with the spontaneous fission and {beta}-decay half… Expand
