Abstract
Excited states in102Sn have been identified for the first time, in an in-beamγ-ray spectroscopic experiment. Twoγ-ray transitions with energies 1472 and 497 keV following the decay of the seniority 6+ isomer with t1/2=1.0(5)μs were unambiguously assigned to102Sn. Due to the very low cross section of about 2µb for producing102Sn in the reaction50Cr(58Ni,1α2n), a highly selective detector setup utilizing NORDBALL ancillary detectors and a recoil catcher device was used. Highγ-ray detection efficiency was achieved with two EUROBALL Ge cluster detectors.
