A new method of the generation of "cold" molecular beam samples of high temperature refractory compounds is described. The method combines the simplicity of an electron bombardment effusive oven for the generation of refractory compounds with the advantage of supersonic expansion. The applicability of the technique is de monstrated by recording the high-resolution laser-induced fluorescence (LIF) spectra of the (0, 0) B 2Σ+-X 2Σ+ (ν00=16855.14 cm-1) band system of CaCl. A comparison with the LIF spectra for a molecular beam sample of CaCl generated by conventional effusive oven techniques is made.
