Abstract

A new /EC branch of % from the isomer of ¹²⁴Cs was identified in a measurement of the decay of ¹²⁴Cs using the spectrometer at TRIUMF. Combinations of -, -, and - coincidence data were used to further investigate the isomeric decay. Six new transitions were observed and their branching ratios were measured.
