The multipole character and &2/Ml mixing ratios of all y transitions following the decay of Ag' to Cd ' have been determined by measuring the 1-2, 1-3, and 1-4 directional correlations, using two 30-cc coaxial Ge(Li) detectors in conjunction with a multichannel coincidence gating system. The analysis of the data clearly demonstrated the necessity for careful investigations of the effects of the Compton background on directional correlation measurements using Ge(Li) detectors. The directional correlation functions for mixed y-y cascades are given in terms of explicitly defined reduced matrix elements and their ratios 6(y").The analysis of the 25 measured directional correlations yielded a consistent set of E2/Ml mixing ratios for all mixed multipole transitions. The E2/Ml amplitude ratios &(y") = (I"+1)(j&A&+lI")/ (I +&((jz Af((I") for the Cd1'~V rays are (energies are in keV): 6(447) = -0.45 + 0.20, 6(620) = -0.80 + 0.50, 6(678) = -0.25 + 0.20, 0(687) = -1.1 ()'4, 6(707) = -1.0 + 0.3, 6(818) = -1.20 +0.15, 6(1384) = -0.37+0.03, and 6(1505) = -0.55+0.10. In terms of the multipole moments (I"+~1O(Rw )I~~I") of Bohr and Mottelson, the E2/Ml moment ratios A = &I, +gllJR(E2) II I,)/ &I"~ql(OR(Ml) II I") in natural units (g =m =c =1) are: A(447) =-8.0 +1.8, (620) =-3.8 +2.4, A(678) = -1.09 +0.88, 6 (687) =-4.7+-g'p, 4(707) = -4,2 +1.3, 4(818) =-4.3 + 0.5, 4 (1384) = -0.79 +0.06, and 4(1505) = -1.08 + 0.20.

Precise intrinsic quadrupole and hexadecapole moments of 233 > 234 > 235 -238 u have been determined from muonic K, L, M, and TV x rays. For 233 ' 235 u seven E2 matrix elements were independently determined. These E2 matrix elements are in good agreement with the adiabatic rotational model; this agreement is further improved if a correction for &K = 1 band mixing is included. The measured hexadecapole moments are in good agreement with shellcorrection calculations and Hartree-Fock calculations.
