Nuclear Orientation of 152Eu in Gold

Abstract

Nuclear orientation of 152Eu in gold in the temperature range 9 mK-1 K has been used to determine the mixing ratios of a number of gamma transitions and the multipolarities of several beta transitions of the 152Eu decay scheme. The results agree closely with those from y-y and y-p angular correlation measurements where these have been done. Our results on the" hyperfine interaction of 152Eu in gold contradict those previously published.
