Coincidence in the Two-Photon Spectra of Li and Li2 at 735 nm

Abstract

A coincidence between the 2S - 3S two-photon transition in the spectrum of atomic Li and the X 1Sg+ E 1Sg two-photon ro-vibrational series of 7Li2 was observed near 735 nm in a heat pipe oven using a tunable laser and thermionic diode detection scheme. The molecular transition obscures one component of the 6Li atomic transition. Selective detection of the atomic transition was obtained by adding an intensity-modulated laser that drives atoms from the 3S to 16P state. The coincident molecular transition and four nearby molecular lines were identified using previously determined Dunham coefficients.
