..gamma..-..gamma.. directional correlations of the 277-583, 511-583, 722-583, 763-583, and 861-2615 keV cascades have been measured. The data support the spin and parity assignments of (J..pi..) = (6-) and (5-) to the 3920 and 3961 keV levels, respectively. The following experimental multipole mixing ratios were extracted from the data: delta (277) =+0.0080 +- 0.011, delta (511) =-0.052 +- 0.045 or -0.68 +- 0.08, delta (722) =+0.31 +- 0.07, delta (763) =-0.01 +- 0.06, and delta (861) = +0.015 +- 0.012. These mixing ratios were also calculated in the framework of the particle-hole model with the following results: delta (277) =+0.0098, delta (511) =+0.0196, delta (722) =+0.1915, delta (763) =-0.0653 or +0.0219, and delta (861) = +0.0154. The two possible values of delta (763) correspond to the two theoretically predicted (5-) states at 4.00 and 4.18 MeV, respectively. (AIP)
