Abstract
The 4He octupole resonance in the 4He(y, p) reaction is investigated by using the generalized R-matrix methodology of Lane and Robson. R-matrix calculations are also utilized to calculate Jn = 3- resonances which dominate the E3 cross section. The calculated 4He(y, p) E3 cross section peaks at a value of 4.69 · 10-3 fm2 at 71.0 MeV excitation energy. Secondary peaks occur at 76.4 MeV (1.84 · 10-3 fm2) and at 80.0 MeV (1.82 · 10-3 fm2).
