Abstract

The branchings (absolute intensities) of γ-rays following the decay of84,85Ge and84,85As have been determined using mass-separated samples. Our results include the first identification of85Ge and the first γ-ray data for84Ge. Values of the delayed neutron emission probabilities, Pn, of84Ge and85As were also deduced from the data, together with a lower limit of this quantity for85Ge. The deduced Pn of about 39 % for the important neutron emitter85As is substantially larger than the values of about 22–23 % obtained in previous indirect determinations.
