Elastic and inelastic scattering of monochromatic photons was used for studying nuclear energy levels in 100Mo; the photons were produced by thermal neutron capture in titanium, copper and vanadium. The decay of the resonances at 7637, 6517 and 6418 keV was studied in detail. The angular distribution of some elastic and inelastic lines was measured and the following spin determinations were made: (keV, Jπ); 535, 2+; 694, 0+; 1063, 2+; 1462, 2+; 2033, 0+; 2040, 2+; 5187, 1; 6418, 1-; 6517, 1-; 7637, 1-. The parities of the last three levels were directly determined using a Compton polarimeter. Total radiative widths were measured and the following results were obtained:Γ(6418) = 50 ± 35 meV, Γ(6517) = 180 ± 100 meV and Γ(7637) = 140 ± 40 meV. The M2 E1 mixing ratios for two primary transitions were obtained.
