The differential cross-sections of the elastic and inelastic α +11B scattering was measured at E(α) = 29 MeV. The analysis of the data by Modified Diffraction Model (MDM) showed that the root-mean- square (RMS) radius of the 11B state 3/2-, E* = 8.56 MeV is ~ 0.5 fm larger than that of the ground state. It is found that the radius of 3/2- (8.56 MeV) state in the 11B nucleus is close to the radii of the Hoyle state in 12C.

We measured differential cross sections for the elastic scattering of deuterons on a 13C target using the U-150M cyclotron at INP, Republic of Kazakhstan. The beam energy of deuterons was 14.5 MeV. As a result, we obtained new experimental data for the d+13C elastic scattering. Those were combined with literature data and analyzed within the framework of the optical model using the Woods–Saxon and the double folding potentials. [ABSTRACT FROM AUTHOR]

Differential cross sections have been measured for the elastic and inelastic scattering of deuterons on 9Be at Ed = 14.5 MeV. As a result, we obtained new experimental data for the d+9Be elastic and inelastic scattering leading to the 2.43 MeV (5/2-) excited state of the 9Be nucleus. The experimental results on elastic scattering were analyzed within the framework of the optical model using the Woods–Saxon and double folding potentials. The theoretical calculations for the relevant excited states were performed using the coupled channel (CC) method. The optimal deformation parameters for the excited states of the 9Be nucleus were extracted. [ABSTRACT FROM AUTHOR]

Angular distributions of scattered deuterons on 7Li nuclei with excitation of the 0.478 MeV (Jπ = 1=2-) level and tritons from the 7Li(d,t)6Li reaction with transitions to the ground (1+) state of 6Li were measured at 14.5 MeV. Analysis of the experimental data was performed in the framework of the optical model and the coupled reaction channels method with taking into account the - and n-transfer mechanisms. The values of the spectroscopic factors and the deformation parameters for the 7Li, 6Li were extracted. [ABSTRACT FROM AUTHOR]

The differential cross-sections of the elastic and inelastic C scattering have been measured at EMeV. The radii of the exited states: 3.09 and 8.86 MeV were determined using the Modified Diffraction Model. The radii of these excited states are larger than that of the ground state of C, confirming the suggestion that the 8.86 MeV state could be an analog of the Hoyle state in C and the 3.09 MeV state has a neutron halo. The possibility of coexistence of various exotic states in the structure of the C nucleus is shown. [ABSTRACT FROM AUTHOR]

The main purpose of this work is to find optimal optical parameters and to investigate the transfer mechanism at low energy, close to the Coulomb barrier energy for 15N+16O nuclear systems. Angular distributions were measured at the energy Ecm = 11:59 MeV using stable 15N beams and target Al2O3 with thickness 30 μg/cm². The beam of 15N was accelerated on cyclotron DC-60 (INP, Astana). Registration and identification of charged particles was conducted by ΔE-E method. The data were analyzed within the optical model (OM) and coupled reaction channels (CRC) method. The CRC calculation was used by the program code Fresco [I.J. Thompson, Comput. Phys. Rep. 7, 167 (1988)]. [ABSTRACT FROM AUTHOR]

We have measured the differential cross-sections for the elastic and inelastic scattering of -particles on C target at the isochronous cyclotron U-150 M INP Republic of Kazakhstan. The beam energies of -particles were 29MeV and 50MeV. As a result of research we obtained new experimental data for the + C elastic scattering and inelastic one leading to the 3.68 (), 6.86 () and 7.5 ()MeV excited states of 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 C nucleus were extracted. [ABSTRACT FROM AUTHOR]

Angular distributions of deuterons elastically and inelastically scattered on 7Li nuclei with excitation of the 0.478 MeV (Jπ = 1/2-) level, and tritons from the 7Li(d; t)6Li reaction, corresponding to transitions to the ground (Jπ = 1+) and low-lying excited states (Jπ = 3+ and 0+) of the 6Li nucleus were measured at the 25 MeV energy. The experimental data were analyzed within the framework of the coupled reaction channels and a modified distorted-wave methods. The values of the spectroscopic factors and the asymptotic normalization coefficients for the 7Li → 6Li + n vertex were extracted. [ABSTRACT FROM AUTHOR]

new measurement of differential cross sections for elastic pLi scattering in the energy range 0.35-1.2 MeV was performed. A partial-wave analysis of the data obtained in this way was carried out, and potentials simulating the pLi interaction were constructed. Various experiments devoted to studying elastic pLi scattering over the broad energy range of 0.5-50 MeV were analyzed on the basis of the optical model. By using the potentials obtained from the partial-wave analysis, the possibility of describing the astrophysical S factor for radiative proton capture on Li at low energies was considered within the potential cluster model involving forbidden states.

At an energy of 25 MeV and in the angular range 7°−175° in the laboratory frame, angular distributions were measured for elastic deuteron scattering on 6Li nuclei and for the respective inelastic-scattering processes accompanied by the transitions to the ground state (1+) of the 6Li nucleus and to its excited state at E x = 2.186 MeV ( Jπ = 3+). The resulting data were analyzed on the basis of the optical model of the nucleus and the coupled-reaction-channel method with allowance for the mechanism of alpha-particle-cluster exchange. It is shown that only upon including, in the analysis, channel coupling and the exchange mechanism can the experimental cross sections for elastic and inelastic scattering be reproduced over the entire range of angles.

A unified description of existing experimental data on alpha-particle scattering by 6Li over the broad energy range from 18 to 166 MeV was obtained with allowance for channel-coupling effects and mechanisms involving the exchange of a deuteron cluster. Angular distributions were analyzed on the basis of the optical model and the coupled reaction channels method. It was shown that the inclusion of channel coupling and the contributions from one- and two-step exchangemechanismsmakes it possible to describe special features of the behavior of differential cross sections for both elastic and inelastic scattering in a full energy range. Optimum values found for the parameters of optical potentials agree with the parameters of the global potential proposed previously for nuclei in the mass region A > 12. [ABSTRACT FROM AUTHOR]
