Radiative decay of unbound levels in 14N

Abstract
The gamma decay properties of 10.43-, 10.1-, 9.7-, 9.51-, and 8.91-MeV levels are studied by the 13C(p, γ) reaction. The natural widths, gamma decay widths, branching ratios, and multipole mixing ratios are determined. The gamma branching ratios are generally in good agreement with earlier works. However, it is found that the previous (p, γ) measurements overestimated the gamma transition strengths. The results are compared with shell model calculations. Also, a phenomenological description is attempted for a few 14N levels.
