摘要：

We account for the different symmetries of the 2 S-1,S-3 helium excited states in a quasiclassical description of the knockout mechanism, augmented by a quantum shake-off contribution. We are thus able to formulate the separate contributions of the knockout and shake-off mechanisms for double photoionization for any. excess energy from the 2 S-1,S-3 states. Photoionization ratios and single-differential cross sections calculated for the 2 S-1,S-3 excited states of helium are found to be in very good agreement with recent theoretical results.
