Abstract

The experimental study of the fusion of light neutron-rich nucleus ⁸He with ²⁰⁶Pb is reported in this work. A fusion stack of ²⁰⁶Pb targets has been used for this study. The most prominent evaporation residue (²¹⁰Po), which has half-life of 138 days and decays by alpha emission, is populated in the reaction. Radiochemical analysis technique is used to extract the yield of this evaporation residue.
