Abstract
Pumping the resonance transition Ca 4s2 1S0 to 4s4p 1P1 at lambda =422.7 nm with the linear polarized light of a ring dye laser the subsequent excitation by the linear polarized VUV light of the synchrotron radiation source BESSY was used to investigate the photoionization process from laser-excited aligned Ca atoms. Using the dependence of the photoelectron signals on the polarization axes of both radiation sources the symmetry character of core-resonances 3p53d4s4p was determined.Keywords
