Calculations of long-range three-body interactions for He($n_0{}^{\lambda }S$)-He($n_0{}^{\lambda }S$)-He($n_0^{\prime }{}^{\lambda }L$)

Pei-Gen Yan, Li-Yan Tang, Zong-Chao Yan +1

We theoretically investigate long-range interactions between an excited $L$ state He atom and two identical $S$ state He atoms, for the cases of the three atoms all in spin singlet…
