Decay Scheme ofSb124

Abstract
The beta- and gamma-rays emitted by Sb124 (60d) have been investigated with the help of Geiger-counter coincidences. We find that the hard beta-ray of 2.4 Mev is followed by one gamma-ray, while the soft beta-ray of 0.7 Mev is followed by two gamma-rays. The intensity ratio of the hard to the soft beta-rays is found to be about 1:1.
