We present results of effective range theory
calculations of nondissociative electron attachment to SF6
molecules and CO2 clusters. The first process is strongly
influenced by the SF virtual state, and the second by
vibrational Feshbach resonances associated with electron capture
by the long-range polarization field of the cluster with
simultaneous vibrational excitation of one molecular unit. We also
study how both processes depend on the initial vibrational
excitation of the target. We obtain a noticeable dependence of the
attachment cross-section on the symmetric stretch vibration of
SF6, although it does not lead to a significant temperature
dependence at low electron energies.
