Abstract
The elastic and inelastic scattering of Be-7 from C-12 have been measured at an incident energy of 35 MeV. The inelastic scattering leading to the 4.439 MeV excited state of C-12 has been measured for the first time. The experimental data cover an angular range of theta(cm)= 15 degrees - 120 degrees. Optical model analyses were carried out with Woods-Saxon and double-folding potential using the density dependent M3Y (DDM3Y) effective interaction. The microscopic analysis of the elastic data indicates breakup channel coupling effect. A coupled-channel analysis of the inelastic scattering, based on collective form factors, shows thatmutual excitation of both Be-7 and C-12 is significantly smaller than the single excitation of C-12. The larger deformation length obtained from the DWBA analysis could be explained by including the excitation of Be-7 in a coupled-channel analysis. The breakup cross section of Be-7 is estimated to be less than 10% of the reaction cross section. The intrinsic deformation length obtained for the C-12*( 4.439 MeV) state is delta(2)= 1.37 fm. The total reaction cross section deduced from the analysis agrees very well with Wong's calculations for similar weakly bound light nuclei on C-12 target. (C) 2022 The Author(s).
