摘要
Formation of metastable fragments has been investigated in the vicinity of the Cl 2p ionization thresholds of HCl Efficient productions of H* fragments with their counterpart of Cl(n+) ions are observed around the ionization thresholds. The formations of H*+Cl(n+) pairs result from the dissociation of high-Rydberg HCl(+) states that are populated either by spectator Auger decay from the inner-shell excited states or by the recapture of slow photoelectrons into the Rydberg orbitals. In addition, H* fragments are shown to be produced through the dissociation of HCl(2+) states formed via normal Auger decay of the Cl 2p core-hole states.
