The nucleus 102Sn, which is the lightest Sn isotope with known excited states, was investigated with the 50Cr(58Ni, α2n) reaction using delayed in-beam γ-ray and conversion-electron spectroscopy. The experimental setup was designed to study the decay of μs-long isomeric states by placing γ-ray and electron detectors behind the focal plane of the Fragment Mass Analyzer at the Argonne National Laboratory. A 44 keV conversion-electron line corresponding to the (6+) → (4+) transition in Sn was identified and a half-life of 0.62+0.43-0.19 μs was measured for the (6+) state. From the available experimental information neutron effective charges from 1.6 to 2.3 e were deduced, based on the comparison with different shell-model calculations.
