Transition region spectroscopy of dialkali halides: Sodium(2)chloride and sodium(2) + atomic fluorine going to sodium fluoride + sodium.

摘要

Molecular beam chemiluminescence from Na;In a second experiment, two lines of an argon ion laser are crossed with a single Na/NaCl beam in an effort to observe resolved laser-induced fluorescence of the stable molecule Na;Finally, a detailed description is given of the f/2 spectrograph that was developed in this laboratory. The instrument observes a 100 nm wavelength region simultaneously, images atomic lines to a full-width-half-maximum (fwhm) of 2 nm, has a photocathode quantum efficiency of 3.1% at 800 nm, and exhibits only 36 counts per second dark current.
