ABSORPTION SPECTRA OF METAL ATOMS IN INERT SOLIDS.
Abstract
The absorption spectra of lithium, sodium, indium, mercury, and cadmium in solid argon, krypton, and xenon were obtained at temperatures between 4.5 and 30.0K. The absorption spectra of these trapped atoms exhibit multiple structure. These multiples are explained by assuming that one component results from isolated metal atoms in the inert solid and that the remaining components are due to interacting pairs of metal atoms trapped at nonnearest-neighbor substitutional sites. The energies of the interacting pairs of atoms were obtained from diatomic potential curves. The assignments of the isolated components were confirmed by concentration studies or by selective bleaching of the components. The shift of the component due to well isolated atoms in the inert solid with the energy for the atoms in the gas phase (free atoms) are compared to calculated shifts using a Lennard-Jones (6-12) potential for the interaction between the trapped atom and the inert host atom.
