摘要：

Photodetachment cross section measurements have been performed on the Si-(3s(2)3p(3) S-4) ion using a pulsed dye laser and non-linear optical techniques in the photon energy region close to the 3s threshold. A deep window resonance observed at a photon energy of 5.2 eV is a clear manifestation of electron correlation resulting from the interaction of the 3p-->epsilon s, epsilon d continua with the 3s(2)3p(3)-->3s3p(4) autodetaching resonance. The experimental resonance parameters are compared with theoretical predictions.
