New results in photoionization of laser-excited atoms

The use of high-spectral resolution VUV-photon beams in atomic photoionization experiments has significantly increased over the past few years, owing to the number of operating third generation synchrotron radiation sources and associated high-resolution beam lines. For laser-excited atoms, however, the number of experiments is still low, because of the difficulties in combining the use of these two widely-different photon sources. In the following, we will present the results of high-resolution photoionization experiments performed by combining a cw dye laser and the photon beam available at the 10.0.1 station of the Advanced Light Source.
