Accurate determination of the pKωK value and the fluorescence yield ωK of Sr after electron capture decay of88Y

Abstract

The Prco~ value of Sr following 88y decay has been determined to be PKO)K= 0.613 + 0.004 using two independent methods for the measurement of the K x-ray emission rate and a calibrated 7-ray spectrometer for the determination of the disintegration rate. With this result and a K-capture probability PK=0.877_0.003 deduced from literature the K-shell fluorescence yield of Sr is OgK-----0.699-t-0.007.
