Gamma Rays from the Decay of 35-Day Nb

The gamma-ray spectrum from the decay of ${\mathrm{Nb}}^{95}$ has been obtained. No evidence was found for a gamma ray reported at 753 keV; if it is present at all, its intensity cannot be as great as ½% of that of the gamma ray at 765 keV. The energy of the latter was measured to be 765.8±0.4 keV.
