Abstract

Angular distributions for the 13C+14C elastic scattering, the inelastic scattering 14C(13C, 13C(12+)) and the reactions 14C(13C, 12C)15Cg.s, 14C(13C, 12C)15C(52+) have been measured at Coulomb barrier energies. With the exception of the ground-state transfer data all other data could be reasonably reproduced with EFR-DWBA calculations performed up to third order. The failure of the calculations in case of the ground-state transfer is interpreted as being due to the existence of molecular effects namely nucleon promotion at avoided crossings.
