摘要：
High-resolution Auger spectra of doubly excited Be-like neon have been obtained for intermediate collisional velocities (0.89-1.79 a.u.). Ne8+ was produced at high voltage in the Argonne National Laboratory electron-cyclotron-resonance ion source. A differentially pumped helium gas cell was used to study double electron capture. The LMX Auger decays of the Be-like neon are observed with a high-resolution 0-degrees tandem electron spectrometer. High-angular-momentum states are observed to be populated during the collisions and their relative amplitudes change dramatically with increasing collisional velocity.
