Title: Z = 50 core stability in 110Sn from magnetic-moment and lifetime measurements

Abstract

In this study, the structure of the semimagic Sn50 isotopes were previously studied via measurements of B(E2;2 1 + → 0 1 +) and g factors of 2 1 + states. The values of the B(E2;2 1 +) in the isotopes below midshell at N = 66 show an enhancement in collectivity, contrary to predictions from shell-model calculations. This work presents the first measurement of the 2 1 + and 4 1 + states' magnetic moments in the unstable neutron-deficient 110Sn. The g factors provide complementary structure information to the interpretation of the observed B(E2) values.
