Angular distributions of the 15N+12C elastic and inelastic scattering were measured at Elab(15N) = 81 MeV to study the nuclear-nuclear interactions and possible transfer contributions to the scattering. The data were analyzed with the coupled-reaction-channels (CRC) method using the 15N+12C optical potential ofWoods-Saxon shape. The elastic and inelastic scattering as well as the most obvious one- and two-step transfer reactions were included in the channel-coupling scheme. The 15N+12C optical potential and deformation parameters of 15N were deduced. The transfer reaction contributions to the 15N+12C elastic and inelastic scattering channels were estimated. The 15N+12C elastic scattering at 81 MeV was compared with the 14N+12C elastic scattering of 14N beam energy 78 MeV. [ABSTRACT FROM AUTHOR]

Preliminary results of an analysis of experiments devoted to a study of the sensitivity of the 20Ne + 208Pb quasi-elastic angular distributions at two near-barrier energies and the previously measured corresponding barrier distribution to the value of the nuclear quadrupole deformation length of 20Ne are reported.

Angular distributions of the 7 Li( 15 N, 14 C) 8 Be reaction were measured at the energy E lab ( 15 N) = 81 MeV. Data for transfer to the ground and first two excited states in 8 Be were acquired as well as to the 14 C ground and excited states. The reaction data were analyzed within the coupled-reaction-channels (CRC) method. The required 15 N + 7 Li entrance channel potential was taken from the 15 N + 7 Li elastic scattering. The 14 C + 8 Be potential was found by fitting Woods–Saxon form potentials to those generated by double folded real and imaginary potentials in the region of interaction. These generated potentials were then used in the CRC calculations. Proton transfer dominants this reaction, including to the excited states of 8 Be. The reaction dependence on the exit channel potential was examined by using the 13 C + 8 Be potential previously deduced from the 9 Be( 12 C, 13 C) 8 Be reaction and 14 C + 8 Be from the 13 C( 9 Be,  8 Be) 14 C reaction.

Angular distributions of the elastic and inelastic scattering of 15 N ions by 7 Li nuclei were measured at the energy E lab ( N 15 ) = 81 MeV ( E c.m. = 25.77 MeV ) . The data were analyzed within the coupled-reaction-channels method. The elastic and inelastic scattering, spin reorientations of 7 Li as well as the more important one- and two-step transfer reactions were included in the channels-coupling scheme. The parameters of Li 7 + N 15 optical potential of Woods–Saxon form as well as deformation parameters of these nuclei were deduced. The analysis showed that the forward angle elastic scattering is dominated by pure potential scattering whereas the middle and large angle scattering gets a contribution from the ground state reorientation of 7 Li. Contributions from particle transfers were negligible for the present scattering system. The Li 7 + N 15 elastic scattering was compared with that of Li 7 + N 14 at the energies E lab ( N 14 ) = 80 MeV and 110 MeV. Different contributions to the elastic scatterings from other nuclear processes are shown to be responsible for the isotopic difference observed in the large angle scattering. [ABSTRACT FROM AUTHOR]

Angular distributions of the 9 Be + 15 N elastic and inelastic scattering were measured at E lab ( 15 N) = 84 MeV ( E c.m. = 31.5 MeV) for the 0–6.76 MeV states of 9 Be and 0–6.32 MeV states of 15 N. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, spin reorientations of 9 Be in ground and excited states and 15 N in excited states as well as the most important one- and two-step transfer reactions were included in the channels-coupling scheme. The parameters of the 9 Be + 15 N optical potential of Woods–Saxon form as well as deformation parameters of these nuclei were deduced. The analysis showed that the 9 Be + 15 N pure potential elastic scattering dominates at the forward angles whereas the ground state spin reorientation of 9 Be gives a major contribution to the elastic scattering cross sections at the large angles. Contributions from particle transfers are found to be negligible for the present scattering system. [ABSTRACT FROM AUTHOR]

Full angular distributions for 11 B + 14 N elastic and inelastic scattering were measured at E lab ( N 14 ) = 88 MeV ( E c.m. = 38.7 MeV ). The data were analyzed within the optical model and coupled-reaction-channels method which included the reorientations of 11 B and 14 N as well as the more important one- and two-step transfer reactions. The 11 B + 14 N optical potential parameters as well as deformation parameters of these nuclei were deduced. The 11 B + 14 N potential and data were compared with those of previously reported 11 B + 15 N data to explore isotopic differences in the scattering process. As has been shown in other cases of 11 B scattering, the enhanced large-angle elastic and inelastic scattering data mostly arise from the ground-state reorientation of 11 B. [ABSTRACT FROM AUTHOR]

Abstract: Complete angular distributions of the 13C + 18O elastic and inelastic scattering were measured at the energy (). These and the 13C + 18O scattering data taken from the literature at the energies were analyzed within the optical model and coupled-reaction-channels methods. Sets of Woods–Saxon 13C + 18O optical potential parameters were obtained. The 13C + 18O scattering data and deduced potential parameters are compared with those for 12C + 18O and 13C + 16O previously measured and analyzed. The 13C + 18O elastic scattering is well described by potential scattering over its complete angular range. The 13C + 18O inelastic-scattering data were well described over the entire angular range as arising from collective excitations of the states in the target and projectile nuclei.
