The 382-kev transition in Re/sup 183/ was shown to have a conversion coefficient of 1.09 plus or minus 0.14 x 10/sup -2/ which established the trainsition as El. The half-life of the state from which this arises was found to be 7.7 plus or minus 0.5 x 10/sup -9 sec from delayed coincidence measurements, indicating a hindrance factor of 3 x 10/sup 6/ relative to the single particle value. Other transition multipolarities were assigned from their conversion coefficients, L subshell and K/L ratios as obtained from the preceding paper. Amongst these the 170.72-kev isomeric transition is Os/sup 183/ was identified and shown to be M4 with a hindrance factor of 12. Decay schemes for Os/sup 183/ and Os/sup 183m/ are estahlished and good agreement is obtained between the proposed spins and parities and those suggested by the scheme of energy levels in a spheroidal potential as calculated by Nilsson.
