Analytic Description of Nuclei Shape in 78-84,88Kr Isotopes

Abstract

The potential energy surface for 78-84,88Kr around the mass region A 80 have been studied using the IBMP –code where the isometric potential lines are plotted to description the nuclei shape . the 78-84,88Kr isotopes which considered as typical examples of isotopes that exhibit a smooth phase transition from U(5) to O(6) nuclei, since the minimum potential occurs at approximately β=±0.2 which shifted from U(5) minimum value (β =0) to O(6) minimum (β=1) ,this shift increases with mass number
