Abstract

The reaction ¹¹B(α, γ₀)¹⁵N is studied for 6 ≦ E_α ≦ 11.5 MeV (15.5 ≦ E_x ≦ 19.5 MeV). The excitation function measured at θ_lab = 90° displays four strongly excited resonances at E_x = 16.35 ± 0.02, 16.73 ± 0.02, 17.67 ± 0.05, and 19.05 ± 0.05 MeV, and a probable one at E_x = 17.15 ± 0.05 MeV. These data and 14 angular distributions (0 ≦ θ_lab ≦ 135° for 16 ≦ E_x ≦ 18 MeV) have been fitted with the S-matrix “many-levels” formalism. We propose J^π assignments for the first four resonances. The cross section is about four times smaller than in ¹²C(t, γ₀)¹⁵N. We will discuss possible correlations with resonances observed in other reactions leading to ¹⁵N.
