Abstract

Extensive yield-curve and angular-distribution measurements have been made for the Fe54(p,γ0) and the Fe56(p,γ0) reactions. Both yield curves clearly show the envelope of the giant dipole resonance. The giant resonance appears to be broader in Co57 and this is attributed to a greater isospin splitting and to the fact that proton emission from the two isospin components is expected to be more nearly equal. In both cases the angular distributions appear to be somewhat different for the two T components with the difference greater in Co57. [NUCLEAR REACTIONS Fe54(p,γ0), Ep=4.75-16.80 MeV, Fe56(p,γ0), Ep=4.65-17.40 MeV; measured σ(Ep), σ(θ) at many Ep values. Deduced for (γ,p0)σ(Eγ,θ) in giant dipole resonance of Co55,57.]
