Using gaseous sources of 12 and HI containing the radioactive isotopes 124I and 126I effective cross sections for nuclear resonance scattering from the first 2 + states of 124Te and X26Te were measured. Information is obtained about the charging of the nonradioactive molecular partner after EC decay, the interaction of highly charged ions with neutral molecules, and the slowing down of atoms in a Xe buffer gas. Indications of an iodine complex being stable in the gaseous phase are found.
