Resonant scattering models, using nonlocal decay widths, are developed for dissociative
attachment of slow electrons to diatomic molecules. Cross sections are obtained for HCI and
DCl in several initial rotational and vibrational states, and the dependence of the average
attachment cross section upon the rotational and vibrational temperature is examined. For F,
the cross section for ground state molecules agrees well with experiment above 0.2 eV but
shows no zero energy peak. The attachment cross section is higher for vibrationally excited …
