K-Capture Probabilities in the Decay of ¹⁶⁹Yb to ¹⁶⁹Tm

Abstract

Relative K-capture probabilities in the decay of ¹⁶⁹Yb to 472 keV, long lived 379 keV (52 nsec.), and 316 keV (660 nsec.) levels of ¹⁶⁹Tm are measured using the technique of gamma-K X-ray sum coincidence in a single intrinsic Ge detector. The results agree with the theoretical values.
