Conversion electrons from the 9/2+ → 7/2+ transitions in the odd-mass 105,107,111Ag nuclei have been studied in the radioactive decays of 105Cd, 107Cd and 111Pd, respectively. E2/M1 ratios have been deduced for these transitions and the half-lives of corresponding levels in 105,111Ag have been measured by means of the delayed coincidence technique. The reduced E2 transitions probabilities are compared with theoretical predictions.

The 40-to 500-keV region of the internal-conversion-electron spectrum from the decay of Ba 133 has been investigated with an iron-core, 7rV2 double-focusing spectrometer. 53.152(20) keVhave been observed, and their multipolarities have been determined from measurements of the conversion-electron intensity ratios-Li/Lt/Lz and/or K/L. No new lines with intensity greater than 2.3% of the 356K line were found. The 437K line was found to have an intensity less than 0.01% of the 356K line. The multipolarities obtained for the nine observed transitions were compared with previous measurements of ax and 7-7 angular correlations. This comparison resulted in unique spin-parity assignments of J + , | + , § + , f + , and | + for the ground state and the 80.997 (6)-, 160.58 (4)-, 383.79 (7)-, and 436.93 (6)-keV levels, respectively, in Cs 133 . The measurements of K/Ls and L1/L3 for the 161-keV transition are consistent with previous 276-161 7-7 directionalcorrelation measurements only if penetration effects are included with a X value of 45±10 or 180±20, where X is defined as the ratio of the penetration matrix element to the normal 7-ray matrix element.
