Abstract

The level structure of ${}^{12}N$ has been investigated from 2.2 to 11.0 MeV in excitation energy using a ${}^{11}C$ + $p$ resonance interaction with thick targets and inverse kinematics. Excitation functions were fitted using an R-matrix approach. Sixteen levels in ${}^{12}N$ were included in the analysis, several of them are new. Spin-parity assignments, excitation energies and widths are proposed for these levels.
