New observation of the 6Li7Li33Σg+, 13Δg, and 23Πg states and molecular constants with all 6Li2, 7Li2, and 6Li7Li data
Abstract
This paper reports our new observation of the 33Σg+(v=3-7), 1 3Δ g ( v = 2-4), and 2 3Π g ( v = 2-8) states of 6Li 7Li by continuous wave perturbation facilitated optical-optical double resonance spectroscopy. Combining our new experimental term values of 6Li 7Li with the available experimental data of 6Li 2 and 7Li 2, molecular constants and potential energy curves by Rydberg-Klein-Rees and direct-potential-fit techniques have been determined. Born-Oppenheimer breakdown parameters of the Li 2 1 3Δ g and 2 3Π g states are calculated.
