An S matrix, which gives very good fits for the elastic scattering of 16O + 28Si over the angular range 15° < θ < 180°, has been generated at six energies (21 MeV < E(centre of mass) < 35 MeV). The S matrix is composed of a parametric form plus a small statistical term for each partial wave. The properties of the S matrix have been examined in order to deduce the mechanisms involved in the reaction. The 180° excitation function has also been computed.

Angular distributions for the scattering of 29 MeV 3 He-particles by light nuclei have been observed using a photographic plate method. Absolute differential cross-sections for elastic scattering, and for inelastic processes for 2 H, 3 He and 4 He nuclei, are given within the centre-of-mass angular range 20 to 150°. The elastic scattering distributions for the 1 H and 3 He nuclei have been compared with predictions based on resonating group theory.

Bombarding Energy

In this paper, the S-matrix parametrization is adopted to analyze the refractive scattering of [Formula: see text] at intermediate energies systematically and that of [Formula: see text] at 230 MeV. For [Formula: see text], the experimental data containing the Fraunhofer oscillations and the rainbow falloff are reproduced very well by adjusting parameters. The S-matrix parameters and the rainbow angles show evident tendencies as the bombarding energy increases, which are comparable with those of [Formula: see text] elastic scattering on carbon target. For [Formula: see text], the experimental data in the forward direction are reproduced successfully by slightly adjusting the parameters used in the calculation of [Formula: see text] at 210 MeV. The calculated results show that the [Formula: see text] scattering exhibits a comparable transparency with that of [Formula: see text] at intermediate energies.

We have measured the angular distributions for 16 O elastically scattered on 12 C nuclei at energy 28 MeV and also for 12 C ion beam elastically scattered on 11 B target nuclei at energy 18 MeV. These measurements were performed in the cyclotron DC-60 INP NNC RK. Calculations were performed using both empirical Woods–Saxon and double folding optical model potentials. Both elastic scattering and transfer reaction were taken into consideration. We have extracted the spectroscopic factors for the configurations 16 O → 12 C + α and 12 C → 11 B + p and compared them with other calculated or extracted values at different energies from literature. The extracted spectroscopic factor for the configuration 12 C → 11 B + p from the current work is in the range 2.7–3.1, which is very close to Cohen–Kurath prediction. While for the configuration 16 O → 12 C + α, spectroscopic factors show fluctuation with energy which could be due to the well-known resonant-like behavior observed in 16 O + 12 C excitation function.
