SODIUM - RARE-GAS VAN DER WAALS MOLECULES

<p>The intensity of the fluorescent radiation from the red wing of the Na D-lines perturbed by rare-gas atoms has been measured as a function of temperature and rare-gas density. These observations were then combined with a quasistatic analysis to determine the potential well depths and the emission peak wavelengths for ${\rm Na(3P)He}\sb2,$ ${\rm Na(3P)Ar}\sb2,$ ${\rm Na(3P)Kr}\sb2,$ and ${\rm Na(3P)Ar}\sb3$ molecules. The following results were obtained: for ${\rm Na\sp\* He}\sb2,$ {\rm D = 820(110) cm}\sp{-1}, $\lambda = 8400$ A; for ${\rm Na\sp\* Ar}\sb2,$ {\rm D = 1100(150) cm}\sp{-1}, $\lambda = 7200$ A; for ${\rm Na\sp\* Kr}\sb2,$ {\rm D = 1355(180) cm}\sp{-1}, $\lambda = 7400$ A; and for ${\rm Na\sp\* Ar}\sb3,$ {\rm D = 1595(300) cm}\sp{-1}, $\lambda = 8600$ A. These results are consistent with a simple model of the alkali-rare-gas molecules in which the depth of the potential energy well of a given molecule can be accurately represented as the sum of well depths of the individual alkali-rare-gas pairs.</p>
