He and his colleagues investigated many-electron motions in multiphoton ionization and excitation, fifth-harmonic production in neon and argon, strong-field processes in the ultraviolet, generation of very short wavelengths in BaF 2, which produced x-rays 9-13 ?and the kinetic energy distributions of ionic fragments produced by subpicosecond multiphoton ionization of N 2 ( 1988a, 1989b, 1991a ).
