ABSTRACT
A simple scaling argument is proposed to understand the localization of excess electrons in simple fluids and to interpolate numerical results of path integral simulations and reference interaction site—polaron theory. A mapping is found between an impenetrable object of arbitrary geometry and a spherical hard sphere. Numerical simulations of solvated electrons in atomic and diatomic solvents are used to demonstrate the validity and applicability of these scaling and mapping schemes. © 1995 American Institute of Physics.
