Angular distribution and yield studies of the 19F(p,α0)16O and 7Li(p,α)4He nuclear reactions in the proton energy range 0-3-3-0 MeV

The angular distribution of the ¹⁹F(p, a0)¹⁶O and ⁷Li(p, a)⁴He nuclear reactions have been studied for an energy range 1.1 MeV to 2.0 MeV and angular range of 35° - 160°, in addition to the excitation functions for an energy range 0.3 - 3.0 MeV at 150° and from 1.1 - 1.95 MeV at different angles. The observed angular distributions have been corrected to the center-of-mass system and analyzed in terms of Legendre polynomials. Comparison with other previous measurements is also listed, and the spins and parities of prominent resonances in the ¹⁹F(p, ao)^l60 and ⁷Li(p, a)⁴He nuclear reactions are calculated.
