摘要：

The branchings (absolute intensities) of gamma-rays following the decay of Ge-84,85 and 84,85As have been determined using mass-separated samples. Our results include the first identification of 85Ge and the first gamma-ray data for 84Ge. Values of the delayed neutron emission probabilities, P(n), of 84Ge and 85As were also deducted from the data, together with a lower limit of this quantity for 85Ge. The deduced P(n) of about 39% for the important neutron emitter 85As is substantially larger than the values of about 22-23 % obtained in previous indirect determinations.
