At room temperature the C{sub 6}F{sub 6} molecule attaches slow (<1 eV) electrons nondissociatively producing long-lived parent anions. The authors studied the electron attachment and detachment properties of C{sub 6}F{sub 6} in a buffer gas of N{sub 2} for mean energies below 1 eV as a function of temperature T in the range 300 to 575 K. They found that the electron attachment rate constant initially increases slightly with T for T<450 K and subsequently decreases with increasing T and the autodetachment rate constant of C{sub 6}F{sub 6}{sup {minus}{degrees}} increases monotonically as T is raised from 300 to 575 K.
