A great number of researches have been done near the N~50 region and the results showed that manynuclei in this region are spherical[1]. Some shell model calculations using 82Sr as the core, performed in this region, are in good accordance with the observ A great number of researches have been done near the N ~ 50 region and the results showed that many nuclei in this region are spherical [1].
