We present an overview of two recent experiments in which photoelectron angular distributions from light-polarised He and Ne atoms are studied, with the emphasis on theoretical description of photoionisation. Polarised He (Ne) atoms are prepared in the 1s4p, 1s5p, or 1s6p (2p53d) states with linearly polarised synchrotron light and ionised with a tunable infrared laser. The asymmetry parameters extracted from the measured velocity map imaging spectra agree well with the calculated asymmetry parameters.

Abstract
We present an overview of two recent experiments in which photoelectron angular distributions from light-polarised He and Ne atoms are studied, with the emphasis on theoretical description of photoionisation. Polarised He (Ne) atoms are prepared in the 1s4p, 1s5p, or 1s6p (2p53d) states with linearly polarised synchrotron light and ionised with a tunable infrared laser. The asymmetry parameters extracted from the measured velocity map imaging spectra agree well with the calculated asymmetry parameters.File in questo prodotto:
