Abstract
Quasielastic scattering of $^{6}\mathrm{He}$ on a $^{12}\mathrm{C}$ target was measured at 82.3 MeV/nucleon. Special care was taken to treat the background subtraction at very small angles. The measured differential cross-sections show a large enhancement at small angles relative to the Rutherford cross-section, similar to those observed at lower energies for the scattering of halo nuclei. The overall structure of the cross-section is reasonably reproduced by the optical model calculations. The inelastic channels which populate two low-lying excited states of $^{12}\mathrm{C}$ target nucleus were included in the framework of the coupled channel analysis. Further systematic theoretical analysis is encouraged.
