Abstract

The excitation functions of the elastic scattering 12C(p, p)12C and the reactions 12C(p, p′)12C (4.44 MeV) and 12C(p, α)9Bg.s. have been measured at θ = 175° in the region of the first T = 32 state in 13N with high energy resolution. A straightforward resonance analysis of the elastic scattering data yields Γ = 1.10 ± 0.09 keV, Γp = 210 ± 11 eV and ΓpΓ = 0.191 ± 0.017. The results are compared with shell-model predictions. The additionally measured angular distributions of the elastic scattering 12C(p, p)12C above and below the resonance are compared with optical model calculations. The combination of the present results for Γp and Γp/Γ with previous results for Γγ/Γp and ΓγΓp/Γ yields Γγ = 27.0 ± 2.2 eV as a new determination of the 13N(T = 32, 15.07 MeV → T = 12, 0 MeV) γ-decay width. The comparison with the analogous γ-decay in 13C is discussed with respect to the charge symmetry of corresponding ΔT = 1 γ-transitions in mirror nuclei.
