Absolute cross sections for electron impact ionization of C⁺, N⁺ and P⁺ ions have been measured for electron energies from threshold up to 1000 eV, using the crossed beam technique. The measured cross sections for both C⁺ and N⁺ ions are in good agreement with the semiempirical Lotz formula over the whole energy range investigated, and also with those previously reported except for near threshold. The results for P⁺ ions show a more rapid rise from the threshold and larger values around the peak than those calculated with the Lotz formula.
