K-electron capture probability in the decay ofAgm108(127 yr)

Abstract
The K-electron capture probability (Pk) in the decay of Agm108 (127 yr) has been determined from a measurement of the Pd K x-ray intensities as well as from the analysis of the K x-ray gamma-ray sum peak. From the measured value of Pk (0.85±0.04) the ground-state mass difference between Ag108 and Pd108 is estimated as Q+=1926169+ keV.
