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 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]

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]

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.
