Abstract The possibilities for the emission of 4 He and 14C 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 14C 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 14C emission. The role of neutron shell closure (N = 126) in Λ 213Rn daughter and role of proton and neutron shell closure (Z = 82, N = 126) in Λ 209Pb 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 14C emission from normal Ra nuclei are favorable for measurement, we presume that alpha and 14C cluster emission from hyper Ra nuclei can be detected in laboratory in a cascade (two-step) process..
