RESEARCH OF DISCRETE ENERGY LEVELS IN SYSTEMS OF ATOMS.
Abstract
Microwave absorption spectra of nitrogen trifluoride doped argon crystals, at 4K, were taken in the 18 to 49 gc region. Using a model of the doped lattice which neglected exchange effects, absorptions greater than 3 db were estimated. With a broad-band apparatus, limited by a 1 db sensitivity, no absorption was found. A machine program was written for the calculation of the uranyl overlap integrals which yields the Belfords' values. When Hartree-Fock-Slater, instead of the Hartree, uranium solutions are used, preliminary results show the pioverlaps are still larger than the sigma-overlaps although differences between them are less. Infrared absorption spectra of rubidium uranyl nitrate, at 4K, were taken, which contain absorption lines characteristic of the unit cell. These results are part of a larger study, which is continuing, of the behavior of two molecular systems, doped inert gas lattices and uranyl salts. These investigations were undertaken because of the scientific problems involved and in an effort to find new useful materials for quantum electronics applications. (Author)
