Effective deexcitation cross sections of fast beams of Na, Ne, and Li+ in the excited P state at energies of ~160 keV with a N2 gas target are reported. These cross sections are obtained from analysis of the dependence of the effective lifetime on the gas pressure. Results for neon indicate small variations of deexcitation cross section for the different 3p fine structure levels.
