摘要：

We have measured the angle-resolved energy dependence of the electrons emitted over the energy range of the triply excited 2s(2)2p P-2 lithium resonance using synchrotron radiation. We have also calculated the behavior of the angular distribution parameter beta using the R-matrix approximation. Experimental and theoretical results are in good agreement and show deep minima in the 1s2p P-1,P-3 ionic channels, The energy at which the minima occur does not coincide with the resonance energy, but is shifted towards higher energy.
