A unified model description of some nuclei in theN=49 region

Abstract

The unified model has been applied in a description of the structures of⁹¹Mo,⁸⁹Zr and⁸⁷Sr as well as to the lighter strontium nuclei⁸⁵Sr and⁸³Sr. The quasi-particles 1g _9/2, 2p _1/2, 2p _3/2, 1f _5/2, 2d _5/2, 3s _1/2 and 2d _3/2 have been coupled to the vibrations of the cores. An improvement over the earlier shell model calculations is obtained for the strontium nuclei while forN=49 nuclei the prediction of anomalous states populated in some direct reaction studies is achieved.
