The decay of oriented /sup 110/Ag/sup m/ has been studied through singles and coincidence counting. The nuclear polarization was obtained by using a dilution refrigerator and the hyperfine field in iron. Ge(Li) singles spectra yielded the following E2/M1 mixing ratios: delta (477 keV) = - 0.40 +- 0.06, delta (678 keV) = - 0.36 +- 0.03, delta (687 keV) = - 1.65 +- 0.09, delta (707 keV) = - 1.42 +- 0.07, delta (1384 keV) = -0.39 +- 0.02, delta (1505 keV) = -1.09 +- 0.09. In a time-reversal invariance test the phase angles eta of the mixing ratio delta = *delta*e/sup i/eta were measured through the observation of ..gamma..-..gamma.. directional correlations in the daughter /sup 110/Cd. Three NaI detectors allow six coincidence combinations to be measured for both the 1505-658 keV and the 1384- (885) -658 keV cascades. We found sin eta (1505 keV) = (1.5 +- 2.2) x 10/sup -3/ and sin eta (1384 keV) = (- 1.7 +- 5.1) x 10/sup -3/, consistent with time-reversal invariance. The g factor of the 658 keV state in /sup 110/Cd was determined to be 0.28 +- 0.05.
