Abstract

Threshold photoelectron-Auger electron coincidence spectroscopy has been applied to the Coster-Kronig transitions from the Cl 2s core-hole state of HCl. The use of coincidence spectroscopy reveals Auger lines associated with the Cl 2s core-hole state in the sub-natural linewidth regime. The coincidence Auger spectrum reveals two band structures corresponding to the formation of HCl²⁺[(Cl 2p)^-1 (V)^-1] doubly ionized states via Coster-Kronig transitions, which are only weakly observed in the normal Auger spectrum. These structures are tentatively assigned to HCl²⁺[(Cl 2p)^-1 (V)^-1] doubly ionized states with the 2π or 5σ valence (V) holes.
