Abstract

We have performed shell model calculations for neutron deficient even <superscript>102-108</superscript>Sn and odd <superscript>103-107</superscript>Sn isotopes in sdg<subscript>7/2</subscript>h<subscript>11/2</subscript> model space using two different interactions. The first set of interaction is due to Brown et al. and second is due to Hoska et al. The calculations have been performed using doubly magic <superscript>100</superscript>Sn as core and valence neutrons are distributed over the single particle orbits 1g<subscript>7/2</subscript>, 2d<subscript>5/2</subscript>, 2d<subscript>3/2</subscript>, 3s<subscript>1/2</subscript> and 1h<subscript>11/2</subscript>. In more recent experimental work for <superscript>101</superscript>Sn [I. G. Darby et al., Phys. Rev. Lett.105 (2010) 162502], the g.s. is predicted as 5/2<superscript>+</superscript> with excited 7/2<superscript>+</superscript> at 172 keV. We have also performed another two set of calculations by taking difference in single particle energies of 2d<subscript>5/2</subscript> and 1g<subscript>7/2</subscript> orbitals by 172 keV. The present state-of-the-art shell model calculations predict fair agreement with the experimental data. These calculations serve as a test of nuclear shell model in the region far from stability for unstable Sn isotopes near the doubly magic <superscript>100</superscript>Sn core.
