Abstract
The intensity of the unique first-forbidden 4.708-MeV outer branch of the spectrum, leading to the 110-keV hole state in , has been determined as per decay. Consequently, the comparative half-life is sec, and the strength of the transition is . This result was found from the analysis of coincidence spectra obtained from reactor-irradiated water samples that had been enriched in . An upper limit of 6 × is set on the branching of the 197-keV level decay in through the 110-keV state. The results can be used to infer the extent of wave-function admixture (core excitation) in the ground state of .
