G factors in 116,118,120Sn : Sensitivity to configurations near the Fermi surface

Abstract The transient-field technique has been used to measure the g ( 2 1 + ) values in 116,118,120 Sn, simultaneously, relative to each other and to the well-known g ( 2 1 + ) values in the stable even Pd isotopes. The g factor in 118 Sn, which has a small positive value, evidently differs from those in 116 Sn and 120–124 Sn, which have small negative values. This behavior is investigated through shell model calculations. The experimental g factors are also compared with recent QRPA and RQRPA calculations.
