ResumoThis Rapid Communication reports fully quantum-mechanical calculations of inelastic-scattering cross sections for ${\mathrm{Li}}_{2}^{\mathrm{*}}$(${\mathrm{v}}_{\mathrm{i}}$,${j}_{i}$) +Ne\ensuremath{\rightarrow}${\mathrm{Li}}_{2}^{\mathrm{*}}$(${v}_{f}$,${j}_{f}$)+Ne with 40\ensuremath{\le}${j}_{i}$\ensuremath{\le}100. The calculations are performed within the coupled-states approximation. They reveal large cross sections for vibrational relaxation to remarkably narrow final-rotational-state distributions. The theoretical cross sections reproduce the \ensuremath{\Delta}j=-4\ensuremath{\Delta}v correlation observed experimentally. Comparison of the quantum-mechanical results to classical trajectory calculations confirms the accuracy of the latter procedure.
