Abstract: In some nuclei along the drip-line, for example the exotic nuclei 11Be, an energy level inversion between the 2s and 1p states occurs. Interest in the mirror state of 11Be on the proton rich side, 11N, resulted in a continuation of an earlier study searching for resonances in this nucleus. The experiment involved the resonance scattering reaction 10C + p in inverse kinematics performed at the NSCL at MSU. Preliminary analysis of the data shows evidence for three energy states above the 10C + p threshold with energies 1.3, 2.1, and 3.1 MeV. Using a potential-model analysis, these states can be interpreted as the ground and first two excited states of the 11N system.
