Abstract
The search and study of quasi-molecular resonances in the 31P composite system populated via two entrance channels are performed with two different experimental techniques. The 16O + 15N reaction products have been studied by the γ-ray detection method at cm. energies ranging from 15.5 MeV to 36.1 MeV. Binary channels of the 16O + 15N and 12C + 19F collisions have been studied by using the kinematical coincidence method at 26 incident energies ranging from Ec.m. = 20.6MeV to 33.5MeV for the first system, and at energies corresponding to the same excitation energies of the composite system for the second system. The 16O + 15N reaction exhibits two prominent gross structures in the large angle elastic scattering excitation function correlated with the resonant structures observed in inelastic channel γ-ray yield measurements. Spin assignments were tentatively made for the two resonances. On the contrary, no such structures can be clearly established in the 12C + 19F system where only indications of non-correlated structures in various channels have been observed.
