Conversion-electron--gamma and gamma--gamma directional angular correlations in $sup 160$Dy
Gamma-- gamma and conversion-electron - gamma angular correlations in / sup 160/Dy have been measured for the 298 keV-966 keV and 298 keV-879 keV cascades. Particle parameters of the 966-keV E2 transition were determined to be b/sub 2/(E2; e/sub K/) == +1.23 plus or minus 0.08 and b/sub 2/(F2; e SIGMA L + SIGMA M) = +1.27 plus or minus 0.23. The multipole mixing ratio for the 298- keV radiation was determined to be delta (M2/E1) = +0.04 plus or minus 0.01, and the value delta (E2/M1) = --q3 plus or minus 2 for the 879-keV was confirmed. The EO- E2 mixture parameter for the 879-keV transition was determined as q/sub K/ = 0.03 plus or minus 0.09, assuming penetration effects to be negligible. (auth)
