    "abstract": "The CALTECH gamma-transition experiment testing time reversal symmetry via\nthe E2/M1 mulipole mixing ratio of the 122 keV gamma-line in Fe-57 has already\nbeen performed in 1977. Extending an earlier analysis in terms of an effective\none-body potential, this experiment is now analyzed in terms of effective one\nboson exchange T-odd P-even nucleon nucleon potentials. Within the model space\nconsidered for the Fe-57 nucleus no contribution from isovector rho-type\nexchange is possible. The bound on the coupling strength phi_A from effective\nshort range axial-vector type exchange induced by the experimental bound on\nsin(eta) leads to phi_A \u003c 10^{-2}.",
