Radiative Decay of the Metastable State Hg(63P2) in an Atmosphere of Ar Atoms

Abstract

Abstract We report on the experimental and theoretical study of qusimolecular emission near the forbidden atomic line Hg(63P2-61S0) in a mixture of mercury vapor with argon. The experimental profile is a continuous band in the range 2230 - 2275 Å with a maximum at about 2255 Å. By using the semiempirical method of quasimiolecular term analysis and available experimental potential curves the interaction potentials of the excited atoms Hg* + Ar and the probabilities of the radiative transitions are determined. Based on them quasimolecular emission spectra are calculated.
