Abstract

Absolute total cross sections for excitation of the Be-like ions C²⁺, N³⁺ and O⁴⁺ at electron energies close to the thresholds have been measured. For all three ions, cross sections for the resonance transition 2s² ¹S → 2s2p ¹P were determined. Theoretical cross sections calculated using close-coupling approximations are in reasonably good agreement with the measured cross sections. Some data were also obtained for transitions from the metastable 2s2p ³P states of C²⁺ and O⁴⁺.
