✦ Synopsis

We present the extreme ultraviolet (EUV) emission spectrum of COr induced by electron impact at 200 eV. There are 36 spectral features which are identified with a resolution of 0.5 nm over the wavelength range of 40 to 125 nm. Absolute emission cross sections were obtained for each of these features. The EUV emission spectrum induced by electron impact consists of atomic multiplets of C I, II and 0 I, II, III as well as CO and CO+ molecular band systems produced by dissociative excitation. The C I (119.4 nm) multiplet is the strongest feature of C I with a peak cross section of 3.61 x lO-'9 cm2 at 200 eV. The strongest feature of 0 I in the EUV spectrum is the 0 I (99.0 nm) multiplet with a peak cross section of 3.59 x 1 O-l9 cm' at 200 eV.
