Abstract

He42–alkali-metal triatomic molecular systems are studied using the adiabatic hyperspherical representation. By adopting the best pairwise He-He and He-X interaction potentials, we search for weakly bound states of He42X systems with X=6Li, Li7, Na23, K39, K40, K41, Rb85, Rb87, and Cs133. We consider not only zero total angular momentum J=0 states, but also J>0 states. We find that the He426Li and He427Li systems each possess two bound states with JΠ=0+ symmetry and none with J>0, while the other He42–alkali-metal species are found to support one 0+ and one 1 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.
