The reaction 15N(e, t0) between 20 and 25 MeV
1979
The differential cross section for the reaction 15N(γ, t0) at θlab = 90° has been obtained for excitation energies between 20 and 25 MeV by the measurement of a triton energy spectrum from the reaction 15N(e, t0)e′12C. A virtual photon analysis was used to extract the photodisintegration cross section from the electrodisintegration data. Comparison of this cross section to the cross section at lower excitation energies shows that the 15N(γ, t0) strength is concentrated in the region between 16 and 21 MeV. Comparison of the (γ, t0) cross section with those of other photodisintegration channels suggests an isospin separation energy of 6 MeV.
