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