Research Abstract

Nuclear structures of unstable nuclei in the "island of inversion" region have been investigated experimentally. Nuclear radii and the information about the valence nucleon have been measured and studied using radio active beam. The important changes of the nuclear structure of the nuclei in this region have been reported in the Phsycs Letter B.
