We have measured the differential cross-sections for the elastic as well as inelastic scattering populating the 2.43[Formula: see text]MeV [Formula: see text] excited state in [Formula: see text] using [Formula: see text] beams at energies of 30, 40 and 47[Formula: see text]MeV on a [Formula: see text] target. The experimental results for the elastic scattering were analyzed within the framework of the optical model using the Woods–Saxon and double-folding potentials. The theoretical calculations for the concerned excited states were performed using the coupled-channel method. The optimal deformation parameters for the excited states of [Formula: see text] nucleus were extracted.

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.

The scattering of 100-MeV protons from 11B and 16O has been studied. An optical-model analysis of the elastic scattering on these nuclei has been performed and a consistent set of optical potential parameters which gave a good fit to the experimental results was obtained. In the inelastic scattering on 11B, it has been found that the first and third excited states were weakly excited whereas the second excited state was fairly strongly excited. The results were explained in terms of the unified model.

Theoretical Results

The effect of the deformed surface diffuseness on the elastic scattering reactions with actinide and lanthanide targets is examined. The elastic scattering cross-sections are calculated by assuming the spherical structure for the projectiles and both spherical and deformed structures for the target nuclei. The theoretical calculations are performed by using spherical and deformed Broglie–Winther potentials for the real potential and the Woods–Saxon potential for the imaginary potential in the framework of the optical model. Finally, the effect of the angle dependence on the deformed surface diffuseness for two different orientation angles such as 0 = п/4 and 0 = п/2 is studied. All the theoretical results are compared with both one another and experimental data.

The 12 C ( 3 He, α) reaction was also observed. The elastic scattering distributions have been analyzed in terms of an optical model.

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.

Pseudopotential Calculations

Our earlier pseudopotential calculations on electrons colliding with argon and krypton are extended to consider the elastic electron–helium scattering system. In this paper, we present detailed results for phase shifts, differential, total, and momentum-transfer cross sections for this system for incident electron energies in the range from 0 to 20 eV. These agree very well with existing experimental data and with other theoretical calculations.

The relativistic description of the proton-nucleus elastic scattering can be considered within the framework of a relativistic optical potential model. The elastic scattering of proton with the nuclei 12 C , 16 O , 20 Ne , and 24 Mg at 800 MeV and 1.04 GeV are studied for relativistic and nonrelativistic treatments. The real optical potentials and the differential cross sections of these reactions are calculated. The obtained results are compared with the corresponding results obtained from the calculation depending on the Woods–Saxon optical potential which were adjusted to fit the experimental data. The present results are in good agreement with the experimental data.

In this work, we simultaneously reanalyzed the differential elastic scattering cross-sections ([Formula: see text]) and the vector analyzing power ([Formula: see text]) of [Formula: see text]He elastic scattering. This analysis was performed using the folded optical model for both real central and spin-orbit (SO) potentials, respectively. For the imaginary central, we used the usual Woods-Saxon (WS) form. Three different model density distributions are used to calculate the potential. We aimed to examine the applicability of the microscopically derived SO potential and the structure effect of 6He nucleus. The presence of the [Formula: see text] experimental data of [Formula: see text]He makes it interesting for this study. Our calculations showed that the three densities gave similar predictions for the cross-sections data. The three microscopic SO potentials calculations of [Formula: see text] are not in a good agreement with the experimental data. We concluded that the SO formalism in its current form needs more investigations for exotic halo nuclei.

In this work, the elastic scattering of 6Li+[Formula: see text]Si system at wide range energies from 76 to 318[Formula: see text]MeV is analyzed. The analysis is carried out in the framework of the optical model (OM). Two different methods are adopted for nuclear optical potential of this system. The first method is the double folding cluster (DFC) for the real part supplied with an imaginary part in the Woods–Saxon (WS) form. In the second one, the double folding (DF) model based upon São Paulo potential (SPP) is used as real and imaginary parts each multiplied by a corresponding normalization factor. For [Formula: see text]Si, the full [Formula: see text]-cluster density is considered while the [Formula: see text]-deuteron ([Formula: see text]–[Formula: see text]) structure is considered for 6Li. Therefore, the DFC real central part is calculated by folding both [Formula: see text]–[Formula: see text] and [Formula: see text]–[Formula: see text] effective interaction between target and nuclei over the cluster densities of the target and projectile. The derived renormalized potentials give a successful description of the data. The present results are in good agreement with the previous work. This agreement confirms the validity of the present methods to generate nucleus–nucleus optical potentials.
