✦ Synopsis

Angular distributions of the 11 B + 14 C elastic scattering and inelastic scattering for transitions to a few excited states of 14 C were measured at E lab ( 11 B) = 45 MeV over the full angular range. The data were analyzed within the coupled-channels method. Contributions from one-and two-step transfer reactions were found to be negligible. Quadrupole deformation of the 14 C ground state was deduced to be negative, the deformation of the 8.318 MeV (2 + ) state was found to be similar to that of the ground state. The single particle model calculations reproduced the experimental data for transition to the 6.094 (1 -) state of 14 C much better than the collective model analysis. The fit to this experimental data set was improved when we took into account reorientation of 11 B in its ground state and considerably enlarged the radius of the potential binding the neutron to the 13 C core.
