Scaling predictions for radii of weakly bound triatomic molecules

M. T. Yamashita, R. S. Marques de Carvalho, Lauro Tomio +1

The mean-square radii of the molecules ${}^4$He${}_3$, ${}^4$He${}_2{-}^6$Li, ${}^4$He${}_2{-}^7$Li and ${}^4$He${}_2{-}^{23}$Na are calculated using a three-body model with contact interactions. They a…
