13N level structure via the 10B(3He, 3He) elastic scattering

Abstract The ( 3 He, 3 He) elastic scattering cross-sections on 10 B have been measured at E( 3 He ) = 1.5–3.3 MeV and for centre-of-mass angles θ cm = 75.1°, 107.5° and 143.3°. Two complete angular distributions were measured at E( 3 He ) = 2.10 and 2.98 MeV . Scattering anomalies were observed at bombarding energies of 2.10, 2.90 and 2.975 MeV corresponding to excited states in 13 N at 23.25, 23.87 and 23.93 MeV. Resonances were analysed using a R-Matrix approximation, and level parameters have been extracted.
