Abstract

We present results from large-scale shell model calculations of even and odd tin isotopes from Sn134 to Sn142 with a shell model space defined by the 1f7/2, 2p3/2, 0h9/2, 2p1/2, 1f5/2, and 0i13/2 single-particle orbits. An effective two-body interaction based on modern nucleon-nucleon interactions is employed. The shell model results are in turn analyzed for their pairing content using a generalized seniority approach. Our results indicate that a pairing model picture captures a great deal of the structure and the correlations of the lowest lying states for even and odd isotopes.
