The attachment coefficient for iodine in a (1% I/sub 2/+99% N/sub 2/) mixture, 50 Torr total pressure, has been measured in an electron swarm experiment from 1 to 50 Townsends (1 Townsend=1Td=10/sup -17/ V cm/sup 2/). As the temperature was increased from 35 to 110 /sup 0/C, the attachment coefficient increased for any E/N (electric field intensity/gas number density) values greater than 7 Td. These results are compared to other experimental data and an explanation for the temperature dependence, based on the population of upper vibrational states, is presented.
