Physical Review B
The dynamics following the photoionization of neutral Rb and Cs atoms residing in a dimple at the surface of a superfluid 4 He 1000 nanodroplet has been investigated within time-dependent density functional theory, complementing a previous study on Ba. The calculations reveal that structured high density helium solvation layers form around both the Rb + and Cs + cation on a picosecond time scale, forming so-called snowballs. In contrast to the Rb + ion, Cs + is not solvated by the 4 He 1000doi:10.1103/physrevb.90.224518 fatcat:jwrq3jek3jf6tpg4mim4dw3lum
