123IN c  2004Sc42: {+123}In isomer was produced via the thermal-neutron induced
123IN2c  fission of {+239}Pu and {+241}Pu. Fission fragments were separated by
123IN3c  the LOHENGRIN mass spectrometer according to their mass to ionic
123IN4c  charge ratios and detected in a |DE gas detector. |g rays were detected
123IN5c  with two large-volume Ge detectors and x rays and conversion electrons
123IN6c  were detected with two Si(Li) detectors. Measured E|g, I|g, |g|g-coin,
123IN7c  |g|g-coin, E(ce), |g(t). Deduced levels, J, |p, T{-1/2}. Comparisons
123IN8c  with shell-model calculations.
123IN cL E$From a least-squares fit to |g-ray energies
123IN cL J$From Adopted Levels. Assignments for excited states are adopted from
123IN2cL this study as proposed by 2004Sc42, based on systematics of neighboring
123IN3cL odd-mass In isotopes and |g decay pattern.

123IN cL J$the simultaneous feeding of the 11/2+ and 13/2+ levels at 1027.5
123IN2cL and 1165.9, respectively, (and no feeding to 9/2+ g.s. and 11/2+ level
123IN3cL at 1027.5), suggests a spin and parity assignment 13/2- or 15/2+ for
123IN4cL this level. The negative parity assignment is preferred by analogy with
123IN5cL the heavier In isotopes, but a positive parity cannot be completely
123IN6cL ruled out (2004Sc42).
