Laser-induced photodissociation of ions

The book describes experiments in which an ion beam was crossed by a laser beam and the number, mass, and velocity of the resulting fragments were measured with the aid of a mass spectrometer. The equipment consisted of a mass spectrometer, a ruby laser, an electron multiplier, fast amplifier, and counter, and these are described. Experiments on the photodissociation of the H2(plus) ion were performed. Methods for approximate deconvolution of the spectra are set forth.
