Abstract

Measurements have been made at two laboratories which indicate that the structure reported at 450-550eV in the electron spectrum from Ar+-Ar collisions by Ogurtsov, Flaks, and Avakyan is spurious. It is argued that the double L vacancies which they invoke to explain the structure are more likely to decay by the two-step Auger process L 2→LM2→M4 than by the one-step process L2→M3 suggested by these authors. Evidence supporting this is found in our electron spectra from P+-Ar collisions, where it is known from energy-loss and charge-state measurements that double L vacancies are produced in phosphorus.
