Abstract
TheK-electron capture probability,P K, in the allowed and non-unique first-forbidden transitions is measured by observing coincidences betweenK x rays and γ rays. The following results are obtained. In Gd151 decayP K to the 349.8 keV level is 0.713 ± 0.015 andP K to the 307.4 keV level is 0.813 ± 0.020. It is also deduced that the decay energyQ EC is 491 +14−9 keV and the spin of the 307.4 keV level is 7/2. In Dy159 decayP K to the 58.0 keV level is found to be 0.803 ± 0.032.
