摘要：

Using highly correlated Hylleraas-type wave functions of S-1 and P-1 symmetry, we show how the harmonic generation spectrum of 1(1)S He (including short wavelength members previously attributed to He+) arise from a radial-angular ''descreening'' mechanism, This provides the first indication that harmonic generation spectrum can arise from strong dynamical electron correlations rather than purely as a ''one-electron phenomenon.''
