The high-resolution Auger electron spectrum of HCl has been measured in the gas phase with the use of electron-beam excitation. The fine structure of the spectrum has been interpreted and compared with the calculated line energies. The energies of the initial states in H${\mathrm{Cl}}^{+}$ and the final states in H${\mathrm{Cl}}^{2+}$ have been calculated in the molecular-orbital linear combination of atomic orbitals self-consistent-field approach, with the correlation effects being taken into account in the frame of the configuration-interaction technique. The relative line intensities have been discussed in the light of the analogy to the Auger spectrum of the next-neighbor and isoelectronic element argon.
