Abstract
–alkali-metal triatomic molecular systems are studied using the adiabatic hyperspherical representation. By adopting the best pairwise He-He and He- interaction potentials, we search for weakly bound states of systems with Li, , , , , , , , and . We consider not only zero total angular momentum states, but also states. We find that the Li and Li systems each possess two bound states with symmetry and none with , while the other –alkali-metal species are found to support one and one bound state. We calculate the bound-state energies of these molecular species and discuss the essential features of the wave functions associated with these bound states.
