Electron-Impact Single Ionization of C3+


Ionization Cross Section vs. Energy for C3+ Legend:
Circles - ORNL data
Solid line (red) - Scaled Coulomb-Born direct (ground state)
Dashed line (green) - Lotz formula (ground state)

Reference: D. H. Crandall et al., J. Phys. B 12, L249 (1979).

Absolute uncertainty: 8% typical near peak of cross section

Estimated metastable fraction of target ions: <1%
