Correction factors for γ-ray relative intensities in the 66Ga radioisotope
We present here strong evidence that recently published values for the relative intensities of γ-ray lines in the 66Ga(β+ + EC)66Zn decay are incorrect at the higher energies (∼ 30% too low at 4.8 MeV). In particular, we find that our current results are consistent with a set of correction factors which were first suggested 20 years ago, but have gone largely ignored until now. Our validation of these little known correction factors will have bearing on experiments which use the 66Ga radioisotope to extrapolate absolute detector efficiencies to higher energies. In particular, we discuss the conclusions of a recent D(p, γ)3He experiment which will be strongly affected by our current results. The astrophysical S-factor data derived from this D(p, γ)3He experiment are now seen to be systematically too low by ∼ 30%.
