The 15N(p, α)12C reaction with polarized protons from 0.34 to 1.21 MeV

A polarized beam was used to measure angular distributions of the analyzing power of the ¹⁵N(p, α)C reaction at 0.34 MeV and at five energies from 0.92 to 1.21 MeV. The analyzing power can be fitted with associated Legendre polynomials, P₁¹ and P¹₂ sufficing to describe the results except near 1.2 MeV where P₃¹ is also required. Polarization excitation functions were measured throughout the entire energy range at angles where the polynomials P¹₂ and P¹₃ are zero. A polarization contour map is given.
