We present a systematic conﬁguration-interaction shell-model calculation on the structure of light tin isotopeswith a global optimized effective interaction. The starting point of the calculation is the realistic CD-Bonnnucleon-nucleon potential. The unknown single-particle energies of the 1d3/2, 2s1/2, and 0h11/2 orbitals and theT = 1 monopole interactions are determined by ﬁtting to the binding energies of 157 low-lying yrast states in102−132Sn. We apply the Hamiltonian to analyze the origin of the spin inversion between 101Sn and 103Sn that wasobserved recently and to explore the possible contribution from interaction terms beyond the normal pairing.
