Production and decay of N/sub 2/(A /sup 3/..sigma../sup +//sub u/) (v=0, 1, 2) states were monitored photoelectrically from the sensitized fluorescence of NO ..gamma.. bands. These states were produced by collisional transfer from excited Xe (1S/sub 4/) which in turn was produced by radiative energy transfer via resonance radiation (147 nm) from a closely coupled Xe flash lamp. The rate coefficient for the deactivation of N/sub 2/(A /sup 3/..sigma../sup +//sub u/) by I/sub 2/ was measured as k/sub I/2= 6.9 +- 1.9 x 10/sup -12/ cm/sup 3//sec. The deactivation by NO itself was measured as k/sub NO/=4.5 +- 0.5 x 10/sup -11/ cm/sup 3//sec.
