InnerShell Ionization in the KElectron Capture Decay of TUNGSTEN181.
Abstract
The probability P(,KK) of double Kshell vacancy production during Kelectron capture in the ('181)W to ('181)Ta transition is measured to be (1.25 (+OR) 0.42) x 10('5) by observing Ta. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). in coincidence with Ta K x rays using high resolution semiconductor detectors. This value is found to be in agreement with the estimate made using Intemann's theoretical calculation of the Kelectron ejection probability, P(,ej), and Mukoyama's ratio of the probabilities for excitation and ejection, P(,ex)/P(,ej). The energy shift of the Ta. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI). with respect to the normal Ta K(alpha)(,1) x ray is found to be 1085 (+OR) 70 eV. The probabilities of Kelectron capture in the decay of ('181)W to the levels at 136.3 and 158.7 keV are found to be 0.152 (+OR) 0.086 and 0.090 (+OR) 0.028 respectively.
