Abstract

In our experiments, a Nd:YAG pumped dye laser (10 Hz, 10 mJ/pulse, 0.1-Å linewidth, and 10-nsec pulse duration) excited along with a wavelength-resolved fluorescence detection technique are used to measure the cross sections of electronic-state scrambling collisions of CaX(A²II_3/2) and CaX(A²II_1/2) with the rare gas Ar or He. The laser-induced fluorescence (LIF) is resolved by a scanning double-grating monochromator. The photomultiplier-tube output signal obtained at the exit slit of the monochromator is led to a boxcar integrator.
