Polarized proton scattering on lithium isotopes at 14 MeV

Differential cross sections, analyzing powers, and double differential cross sections for the 6,7Li(p,p') scattering have been measured at an incident energy of 14 MeV. Experimental procedures and results are briefly described. The experimental data of the elastic scattering have excellently been reproduced by calculations based on the spherical optical model (SOM) and the coupled channel (CC) method. The DWBA and CC calculations have not correctly predicted the analyzing powers in the inelastic channels leading to the 1st and 2nd excited states of 6,7Li. The three-body breakup process observed in the (p,p') continuum spectra has been qualitatively explained by DWBA calculations with the discretized-continuum states. The experimental and theoretical results are compared with neutron scattering data. Studies on proton scattering are valuable for modelling of nuclear reactions and for evaluation of neutron scatterings. (author)
