- Abstract
- A new crossed beams apparatus for measuring absolute electron impact ionization cross-sections of multiply charged ions is described. First measurements are also reported which deal with N/sup 4+/ and N/sup 5+/. The results are in good agreements with those previously obtained by the Oak Ridge group, For N/sup 5+/ a non-negligible signal is observed below the ground state ionization threshold. It is attributed to the presence of ions in metastable states. From the semi-empirical Lotz formula the population of ions in those states is estimated to be approximately 3%.
