| Abstract: | Data are presented which strongly suggest that stabilisation of the excited intermediate (N4+)* complex in the reaction (1) N2+ + 2N2 (rate coefficient k1) occurs via N2 switching whereas for (2) N2+ + N2 + He (rate coefficient k2) it occurs via superelastic He collisions. This explains the differing temperature variations of k1 and k2 previously obtained for these reactions. Drift tube data are also presented which show how k1 varies with N2+/N2 centre-of-mass energy as compared with thermal energy. |
