| 英文摘要 | the two-and three-photon detachment of negative silver ions in a femtosecond infrared laser field is studied using photoelectron velocity map imaging methods. photoelectron angular distributions (pads) are obtained for these detachment channels; these pads change dramatically when the laser wavelength and intensity are changed. theoretical predictions, which are based on the adiabatic keldysh-faisal-reiss saddle point method, are in good agreement with our experiment. the dependence of the pad on the laser wavelengths and intensities is due to the interference between the different partial wave functions. the relative contributions of the different partial waves to the detachment amplitude are altered by changing the laser parameters and, as a result, the shape of the pad. close to the detachment threshold, the two-photon detachment process also follows the wigner threshold law. near the detachment threshold, the large differences between the calculated results and our experimental results indicate that the ponderomotive energy shifts caused by the femtosecond laser fields must be taken into account in the theoretical model. the three-photon detachment of ag- is also observed and compared with theoretical calculations. |
