Thermally-induced electron detachment from collisionally stabilized C[sub 6]F[sub 6] in a buffer gas of N[sub 2] has an activation energy of 0.477 eV. This value agreed well with the electron affinity (0.52 eV) reported by Chowdhury [ital et] [ital al]. and Knighton [ital et] [ital al]. However, it is lower than the value of 0.86 eV for the electron affinity of C[sub 6]F[sub 6] reported by some authors. Based on the difference between these two values, Chen [ital et] [ital al]. suggested that the thermally induced electron detachment we observed for C[sub 6]F[sub 6] in N[sub 2] may be occurring from a low-lying excited state of C[sub 6]F[sub 6]. If this is the case, collisional deactivation of this excited state of C[sub 6]F[sub 6] to the ground state must be very inefficient.
