✦ Synopsis
New experimental time-of-flight distributions arc reported for Lith'z and Li+-CO at two center-of-mass enc&s of about 8 and 16 eV and large scattering anples elab =Z 120°. The Li+--h'z spectra sho\v two widely spaced maxima, whereas the Li+-CO spectra show two and sometimes three maxima. The results Itre consistent with the model of rotational rainbows, and have also been analyzed in terms of an impulsive model involving collisions with the individual znoms of the molcculcs wi1h energy-dependent masses. Classical trajectories for a simple model potential reveal only small contributions from vibrational excitation.
