123SB c 1977Ti03: {+123m}Sn activity was produced by irradiation of 97.8%
123SB2c enriched {+122}Sn with thermal neutrons and 96% enriched {+124}Sn with
123SB3c fast neutrons at Saha Institute of Nuclear Physics. X and |g rays were
123SB4c detected with Ge(Li) detectors and conversion electrons were detected
