| 英文摘要 | the photofragmentation of c6h5i at 266 nn is investigated on the universal crossed molecular beam ma chine, and the translational spectroscopy as well as the angular distribution of i atom is measured. the results reveal that under the laser intensity of 10(r) w/cm(2) the single-photon dissociation competes with multi-photon processes. in single-photon dissociation the anisotropy parameter beta is 0.4 and the average translational energy is only 1.04 kcal/mol, which indicates that this process is a slow predissociation. in two-photon photofragmentation the average translational energy is 51.64 kcal/mol, which accounts for about 35% of the available energy. another photofragmentation channel is even more faster, whose peak in time-of-flight spectra corresponds to four or five photon absorptions. the branching ratio of these three channels is determined to he about 3:3:4. |
