Abstract

Gamma-delayed spectroscopy measurements of 67Fe have been performed at RIKEN,
Japan. The spectra from (p, 2p) and (p, pn) channels show a sharp peak at 367 keV. While the total isomer-yield spectrum presents clearly 2 peaks at 367 and 387 keV. The ratio of these two gammas’ intensity was determined to be equal to 0.126(3), in agreement with previous experiments. The origin of these two gammas could be from different isomers of 67Fe. The half-life (T1/2) of the isomer which decays to the 367 keV level was determined to be equal to 150(10) s, more than twice as long as from previous experiments.
