Notes:
Total integral scattering cross sections have been measured for Li2 molecules in selected rotational and vibrational states up to v=21. The vibrationally highly excited states with energies up to 80% of the dissociation energy were prepared by Franck–Condon laser pumping. With increasing vibrational quantum number the observed cross sections show first a 10% decrease followed by a 20%–25% rise. A model potential has been developed based on an ab initio potential for the vibrational ground state to account for the effect of vibrational stretching. The results provide for the first time direct information on the bond-distance dependence r of the complete potential hypersurface V(R,r,γ) (R distance between centers of mass and γ angle between r and R) of an atom–molecule system.
