Abstract
Angular distributions of the differential cross section of O-16 + C-12 elastic and inelastic scattering in the energy range E-lab = 181 - 1503 MeV were fitted with the full cluster folded approach (DFC1) using the coupled-channels (CC) method by taking into account the effect of the low-lying states, 0(+) and 2(+) (E-ex = 4.44 MeV) for the target nucleus. The cluster transition density is generated macroscopically by deforming the cluster ground state modified Gaussian density distribution of the target nucleus. The coupled-channels calculations with the fitted parameters for the elastic scattering provide a successful description of the inelastic experimental measurements. The obtained results are compared with the finding of the phenomenological Woods-Saxon potential. It was found that the characteristic features of the nuclear rainbow phenomena can be reproduced successfully by our CC calculations with both potentials but fail to reproduce the new Airy minimum of the nuclear rainbow structure. The deduced intrinsic quadrupole moment values, Q(20), derived from the analyses are compared with results of previous studies. The deformation lengths, delta(20), obtained by CC calculations are in agreement with those obtained from the electromagnetic measurement values and those reported in previous studies.
