Abstract
Studies of the H2 molecule using resonantly enhanced multiphoton ionization by multicolor narrowband tunable radiation are discussed. Hydrogen molecules are observed in a loosely collimated molecular beam with a density of approximately 1012/cm3 , formed when they diffuse through a multicollimator assembly. They are ionized by the 308-nm unpolarized radiation of an XeCl excimer laser, which gives 400 per mJ/28-ns pulse. The results show a tail in the kinetic energy distribution of H+ fragments with energies in the 9.8-12.5 eV range. The energy of the high-energy tail of ions agrees with the result of a simple calculation based on direct stripping of both electrons by 14 photons followed by a Coulomb explosion from the range of ground-state internuclear separations of H2. Some results on molecular nitrogen agree with this simple calculation.
