Probable alpha and $14$^C cluster emission from hyper Ac nuclei
Abstract
A systematic study on the probability for the emission of 4^He and 14^C cluster from hyper {207-234}^Ac and non-strange normal {207-234}^Ac nuclei are performed for the first time using our fission model, the Coulomb and proximity potential model (CPPM). The predicted half lives show that hyper {207-234}^Ac nuclei are unstable against 4^He emission and 14^C emission from hyper {217-228}^Ac are favorable for measurement. Our study also show that hyper {207-234}^Ac are stable against hyper 4^He and 14^C emission. The role of neutron shell closure (N=126) in hyper 214^Fr daughter and role of proton/ neutron shell closure (Z =82, N =126) in hyper 210^Bi daughter are also revealed. As hyper-nuclei decays to normal nuclei by mesonic/non-mesonic decay and since most of the predicted half lives for 4^He and 14^C emission from normal Ac nuclei are favourable for measurement, we presume that alpha and 14^C cluster emission from hyper Ac nuclei can be detected in laboratory in a cascade (two-step) process.
