摘要/Abstract

摘要：

The combination of a velocity mapping imaging technique and mathematical transformation is adopted to study the angular distribution of electrons ejected from the Eu 4f⁷6p_1/26dautoionizing states, which are excited with a three-step excitation scheme via different Eu 4f⁷6s6d⁸D_J(J= 5/2, 7/2, and 9/2) intermediate states. In order to determine the energy dependence of angular distribution of the ejected electrons, the anisotropic parameters are measured in the spectral profile of the 6p_1/26dautoionizing states by tuning the wavelength of the third-step laser across the ionic resonance lines of the Eu 6s⁺→6p⁺.The configuration interaction is discussed by comparing the angular distributions of ejected electrons from the different states. The present study reveals the profound variations of anisotropic parameters in the entire region of autoionization resonance, highlighting the complicated nature of the autoionization process for the lowest member of 6p_1/26d autoionization series.
