英文摘要: The wavelength dependence of photoelectron angular distributions (PADs) of two-photon detachment of Cu-has been directly studied by using the photoelectron map imaging. Results show that for the laser field intensity of 6.0 x10(10) W/cm(2), PADs exhibit dramatic change with the external field wavelength. Comparison between the experimental observation and the lowest-order perturbation theory prediction indicates that the pattern of PADs can be explained by the interference of the s and d partial waves in the final state. Relative contributions of s and d partial waves in the two-photon detachment at different laser wavelengths are obtained.
