Helium-cluster decay widths of molecular states in beryllium and carbon isotopes

Abstract

The $\alpha$ particle and ${}^6$He emissions from possible molecular states in beryllium and carbon isotopes have been studied using a mean-field-type cluster potential. Calculations can reproduce well the $\alpha$-decay widths of excited states in ${}^8$Be, ${}^{12}$C and ${}^{20}$Ne. For the nucleus ${}^{10}$Be, we discussed the $\alpha$-decay widths with different shapes or decay modes, in order to understand the very different decay widths of two excited states. The widths of ${}^6$He decay from ${}^{12}$Be and $\alpha$ decays from ${}^{13,14}$C are predicted, which could be useful for future experiments.
