Half lives of the α - decay chains of recently reported new isotopes

Heavy-ion reactions have been playing a crucial role in producing and studying nuclei far away from the stability line. Recently, five new neutron deficient unstable isotopes produced in the collisions of ⁴⁸Ca + ²⁴⁸Cm, carried out at GSI have been reported. The decay energies (E_α) and half-lives of the respective α - decay chains of these new isotopes, ^216₉₂ U, ^223₉₅ Am, ²¹⁹₉₃Np, ²²⁹₉₅ Am and ²³³₉₇ Bk have been measured. Here, we present and discuss the α - Decay lifetimes, calculated in the WKB approximation which requires Q - values and α - daughter potential (V_α−D). The potential V_α−D is calculated in the double folding model
