The theory for solvated excess electrons described in an earlier paper is now applied numerically. For the simple model of an electron excluded from spherical regions of radius d surrounding each ofthe particles in a hard sphere fluid, our results exhibit a rich behavior. At all temperatures for which... Ie> a, where... Ie is the thermal wavelength of the electron and ais the diameter of the hard sphere fluid particles, we find a relatively narrow transition region of solvent densities below which the solvated electron is extended and above which the electron is localized. For... Ie= lOa andd= a12, localization occurs near the solvent densityO. lSa-3• Both the width and location of the transition region increase with decreasing... Ie (ie, increasing temperature). When... Ie= 6a, the region is broad, barely discernible, and located near 0.3 a-3 when d= a12. For... Ie: S Sa, no precipitous behavior is found as density is increased and …
