摘要: We present a theory and calculations of two-photon-resonant three-photon ionization He via the lowest even parity doubly excited state1 S 0 (1). assess importance double relative to single into ionic states. Although is found be quite small in context, our reveal autoionizing states as virtual intermediate suggest contexts which may relatively more efficient.
