| Popis: | The dissociation of H+2, D+2 by lasers in a cross-beam experiment is studied. The kinetic energy spectra of the fragments show the vibrational structure of the primary molecular ions. A ruby laser with light polarization parallel to the ion beam direction was used in most experiments; a preliminary study on D+2 with a tunable dye laser was also performed. The experimental spectra are compared with spectra from ab initio computation using theoretical photodissociation cross sections, Franck—Condon populations, and trajectory calculations by the Monte Carlo method. |
