Abstract

We have measured the cross-section ratio σ(γ,H3)σ(γ,He3) for He4 from 31 to 51 MeV with an incident bremsstrahlung beam and a collimated solid-state telescope at 90° laboratory angle. The results obtained from these data for the total cross-section ratio are consistent with unity for most of the energy range covered, but deviate from this value in the energy region near 44 MeV.

NUCLEAR REACTIONS He4 (γ, H3, He3, Eγ=3151 MeV; measured differential cross-section ratio at 90° (laboratory); deduced total (γ,p)-to-(γ,n) cross-section ratio.
