Multiphoton ionization of CF{sub 3}I clusters by ultraviolet laser radiation
The results of the investigation of the multiphoton ionization of (CF{sub 3}I){sub n} clusters by ultraviolet laser radiation are reported. The yields of the I{sub 2}{sup +} and I{sup +} ions, which are the products of the multiphoton ionization, have been measured as functions of the intensity of the ultraviolet radiation at the wavelengths of 308 and 232.5 nm. The degree of multiphoton ionization has been determined and appears to depend on the wavelength of radiation. The velocity distributions of the products have been measured in detail for various wavelengths and various polarizations of radiation. The anisotropy parameters of the velocity distributions of the produced ions and their kinetic energy have been determined. After analysis of the data, a mechanism of the multiphoton ultraviolet ionization of the clusters under investigation has been proposed. This mechanism depends on the used wavelengths.
