TEMPERATURE-ENHANCED AUTODETACHMENT FROM C-C4F6-ASTERISK

The autodetachment of the long-lived c-C4F6-* anion was found to increase with increasing temperature. T, over the range 300 to 550 K. The autodetachment coefficient, delta, was measured as a function of T in a buffer gas of N2 at a mean electron energy of almost-equal-to 0.33 eV, Under these same conditions the electron attachment coefficient, eta, decreases with increasing T for T greater than or similar to 450 K.
