The scattering of 28.5 MeV 3 He particles by 12 C, 20 Ne and 40 A nuclei

Differential cross-sections for the elastic and inelastic scattering of 28.5 MeV 3 He particles by the nuclei 12 C, 20 Ne and 40 A have been measured by means of a photographic technique. The 12 C ( 3 He, α) reaction was also observed. The elastic scattering distributions have been analyzed in terms of an optical model.

We present the results of the [Formula: see text]-matrix description of the [Formula: see text] elastic and inelastic scattering differential cross-sections between 40 and 240 MeV with allocation of Airy minima of various orders. The first-order Airy minima have been unambiguously identified in the differential cross-sections for elastic scattering and inelastic scattering to the first [Formula: see text] state of [Formula: see text] at energies [Formula: see text] MeV, and the second-order Airy minima — at [Formula: see text] MeV. The angular positions of these minima obey an inverse dependence on energy. The intensities of nuclear refraction and absorption also obey the same energy dependence.

The differential cross sections for 4.3 MeV neutrons elastically scattered from natural samples of U, Bi, and Pb have been measured at laboratory angles of 5, 10, and 15°. In the case of uranium, the data are consistent with calculations based on the nuclear optical model and known electromagnetic interactions. Less satisfactory agreement to the data is obtained in the cross section measurements for lead and bismuth.

Optical potentials for the scattering of K ± from 6 Li and 12 C nuclei are calculated using the Watanabe superposition model in terms of the alpha-particle and deuteron optical potentials. The elastic and inelastic scattering differential cross-sections obtained using these potentials are compared with experimental data. Good fits are obtained without modifying any of the parameters. Further measurements for K ± scattering from 6 Li are stressed.

We have measured the differential cross-sections for the elastic and inelastic scattering of [Formula: see text]-particles on [Formula: see text]C target at the isochronous cyclotron U-150 M INP Republic of Kazakhstan. The beam energies of [Formula: see text]-particles were 29[Formula: see text]MeV and 50[Formula: see text]MeV. As a result of research we obtained new experimental data for the [Formula: see text] + [Formula: see text]C elastic scattering and inelastic one leading to the 3.68 ([Formula: see text]), 6.86 ([Formula: see text]) and 7.5 ([Formula: see text])[Formula: see text]MeV excited states of [Formula: see text]C nucleus. The experimental results on elastic scattering were analyzed within the framework of the optical model using Woods–Saxon potential and the double folding one. The theoretical calculations for the concerned excited states were performed using the coupled channel (CC) method. The optimal deformation parameters for the excited states of [Formula: see text]C nucleus were extracted.
