Multiphoton Ionization of I2, Hi, and Cf3i, and Above-Threshold Ionization inI2,

Abstract

Multiphoton ionization (MPI) spectroscopy of several iodine-bearing molecules has shown that molecular dissociation and subsequent ionization of the atomic fragment is the channel preferred to direct ionization of the molecule. ATI has also been observed. While a number of elegant experiments over the past several years have explored the photoionization of atomic (and xenon in particular) at high field intensities, considerably less has been reported for molecules. Our interest lies in the fragmentation of diatomic and polyatomic molecules at optical field intensities > 10 th the 11th W/sq. cm. and this paper describes the results of experiments in which the photoionization of small iodine-bearing molecules has been studied by time-of-flight photoelectron spectroscopy.
