ABSTRACT

The possibilities for the emission of 4 He and 14 C clusters from hyper 202-235 - Λ Ra are studied using our Coulomb and proximity potential model (CPPM) by including the lambda - nucleus potential. The predicted half lives show that hyper Λ 202- 231 - Ra nuclei are unstable against 4 He emission and 14 C emission from Λ 217- 229 - Ra are favorable for measurement. Our study also show that hyper Λ 202-235 - Ra are stable against hyper Λ 4 He and Λ 14 C emission. The role of neutron shell closure (N = 126) in Λ 213 Rn daughter and role of proton and neutron shell closure (Z = 82, N = 126) in Λ 209 Pb 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 Ra nuclei are favorable for measurement, we presume that alpha and 14 C cluster emission from hyper Ra nuclei can be detected in laboratory in a cascade (two - step) process.
