Absolute cross sections for CO2+, C2+ and O2+ formation from CO+ by el
ectron impact have been measured in the energy range from below the re
spective ionization or dissociative ionization thresholds to approxima
tely 2500 eV. The animated crossed-beams method has been employed. The
cross sections at the maximum are found to be 1.45 x 10(-17), 3.4 x 1
0(-19) and 1.3 x 10(-19) cm(2), for these reactions respectively and t
he corresponding threshold energies are determined to be 27.0 +/- 0.5,
42.3 +/- 1 and 48.1 +/- 1 eV. From an energy analysis of the collecte
d dissociation products (C2+ and O2+) the maximum centre-of-mass energ
y available is found to be 12.1 +/- 1 and 7.2 +/- 1 eV and the width o
f the Franck-Condon transition band available is found to be 2.5 +/- 1
and 5 +/- 1 eV, respectively.
