Vdml. Kalyani et al., MEASUREMENT OF K-ELECTRON CAPTURE PROBABILITY IN THE DECAY OF I-125, Nuovo cimento della Società Italiana di Fisica. A. Nuclei, particles and fields, 109(8), 1996, pp. 1129-1133
The K-electron capture probability (P-K) of the allowed transition in
the decay of I-125 to the 35.46 keV level in the daughter nucleus Te-1
25 was measured using X-gamma internal summing method for the first ti
me. The experimental P-K value was found to be 0.825 +/- 0.035 in agre
ement with P-K (theory) equal to 0.804.
