Abstract
The g factors of the first excited 2(+) states in the Sn-112,Sn-114,Sn-116,Sn-122,Sn-124 isotopes have been measured with high accuracy using the transient field technique in combination with Coulomb excitation in inverse kinematics. The experimental results are discussed in a qualitative way on the basis of empirical single-particle g factors of the relevant proton and neutron orbitals and are compared to a number of different theoretical calculations. The results are found to be best described by shell-model calculations in an extended configuration space. Clear evidence for the contribution of neutron pair excitations from the 1d(3/2) to the 0h(11/2) orbital to the wave function of the 2(1)(+) state in Sn-122,Sn-124 has been obtained.
