Abstract
The authors report strong repulsive van der Waals and dipole-quadrupole interactions in the and potentials of the LiCs molecule dissociating into Li and Cs atoms. Theoretical results derived from second-order perturbation theory are verified by investigating experimentally the wavelength dependence of the quasistatic wings of the Li resonance lines broadened by Cs ground-state atoms.
