The behavior of electron beam initiated discharges in HN{sub 3} and inert gas mixtures for different {ital E}/{ital N} values are presented. These results are the first reported investigations of this highly energetic azide gas under plasma conditions. Using a 3 ns, 600 KeV ionizing electron beam, the temporal decay of the discharge current shows HN{sub 3} {ital is} {ital electronegative}. HN{sub 3} attachment rate constants in Ar are 5.0--10.0{times}10{sup {minus}11} cm{sup 3} s{sup {minus}1} for {ital E}/{ital N} values in the range 1--4 Td (10{sup {minus}17} V cm{sup 2}). With the other inert gases (He, Ne, Kr, and Xe), HN{sub 3} attachment rate constants are 0.5--4.5{times}10{sup {minus}10} cm{sup 3} s{sup {minus}1} for the {ital E}/{ital N} range of 0.5--7.0 Td. Plasma excitation of Ar and HN{sub 3} gas mixtures produce intense N{sub 2}({ital C}{r arrow}{ital B}, {ital v}{prime}=0{r arrow}{ital v}{double prime}=0) electronic transition radiation at 3371 A.
