Measurements of Angular Correlations on 88SrThe 9, 7 and e~L ~' directional correlations have been measured for the keV cascade in 8SSr following the decay of ssy. The observed correlation coefficients are A22 (~, 7) = --0.0784 4-0.0042 and A22 (e~L 7) = 0.0102 + 0.0046. The 7 7 experiment is consistent with a mixing ratio 3(~,)= 0.009 4-0.005 for the 898 keV transition. Using the result of the el~L 7 experiment the most probable value of the ratio of the penetration matrix element to the normal ~,-ray matrix element was determined to be 11=0.034-0.30 showing a normal conversion process. This penetration parameter agrees with a hindrance factor Hw(E1)=2.1 9 10 -3 for the E1 transition.
