Effect of temperature on the autodetachment of C6F6-

At room temperature the C6F6 molecule attaches slow (<1 eV) electrons nondissociatively producing long-lived parent anions. The authors studied the electron attachment and detachment properties of C6F6 in a buffer gas of N2 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 C6F6-degrees increases monotonically as T is raised from 300 to 575 K
