Laser action on the (B–X) band of HgI at 445 nm

Abstract

Dissociative excitation of the HgI (B–X) band system and atomic mercury lines was observed during collisions of CO+ ions with CH3HgI molecules in the laboratory kinetic energy range 100–1000 eV. By the use of the integrated intensity of the most intense band of the (B–X) transition of the HgI radical at 445 nm, emission cross sections were measured at different kinetic energies of these ions.
