AUGER DECAY OF THE DISSOCIATING CORE-EXCITED STATES IN THE HCL AND DCL MOLECULES

High-resolution Auger electron spectra from the decay of the Cl 2p-->s igma excitation in HCl and DCl have been measured. The spectra are an alyzed, separating molecular and atomic features, which are assigned t o transitions to the HCl (5 sigma 2 pi)(4) sigma and Cl (3s3p)(6) sta tes, respectively. Auger line shapes, as affected by the molecular dis sociation, are studied by comparing the experiment with the results of Monte-Carlo computer simulations based on a semiclassical model.
