摘要：

Recoil ion momentum spectroscopy has been used to map the entire five-dimensional momentum space of the photo double ionization of helium at 20 eV above threshold. Angular asymmetry parameters for the relative motion of the electrons and the recoil ion have been determined and are found to be close to similar data at 1 eV above threshold. In addition the asymmetry parameter of one photoelectron is found to be in good agreement with recent theory.
