Abstract
The problem of dissociative ionization at intermediate intensities (10(10)- 10(12) W cm(-2)) was studied using the example of I-2 and the technique of velocity map imaging. Several new phenomena were observed, including a cont inuous distribution of recoil energies peaked at zero-kinetic energy, a set of constant dissociative ionic states, and strong anisotropy of the fragme nt velocity distribution that is diminished by intermediate resonances.
