Two Ge(Li) detectors were used to investigate 7 transitions in ~ 5SGd produced by the decay of tSSEu. Relative intensities were determined for the weak lines at 18.8, 26.5, 58.0, and 86.0 keV. Angular correlations for four 7 cascades were measured. As results, the mixing ratios of the 45.3 and 86.5 keV 7 lines were determined, and it was shown that the sign of the mixing ratio is positive for the 7 line at 18.8 keV and negative for the line at 60.0 keV. Spins 5/2 and 3/2 for the 86.5 and 105.3 keV levels, respectively, are consistent with the data, and spin 5/2 for the 105.3 keV level is inconsistent with it.

In addition, data on the g. s. properties of those A= 159 nuclides whose α decays lead to final states in the A=155 nuclides have been reconsidered. General Policies and Organization ofMaterial: See the introductory pages. General Comments: Where deemed appropriate, rotational-band parameters have been computed and are presented. These parameters are defined according to the following expressions: E(J,K)=E(K)+A[J(J+1)-K 2 ]+B[J(J+1)-K 2 ] 2 ,with the following terms sometimes added for K=1/2, 3/2 and 5/2 bands: +(-1) J+1/2 aA(J+1/2) for K=1/2, +(-1) J+3/2 A 3 (J-1/2)(J+1/2)(J+3/2) for K=3/2, and +(-1) J+5/2 A 5 (J-3/2)(J-1/2)(J+1/2)(J+3/2)(J+5/2), for K=5/2.
