The rate coefficient /? for electron attachment to anthracene has been measured at room temperature using a flowing afterglow Langmuir probe mass spectrometer. A value of 1 x 10e9 cm3 s-t (30% uncertainty) was found, indicating that an activation energy barrier might exist.

β¦ Synopsis
The absolute reaction rate coefficients for electron attachment to CT0 have been measured in the electron temperature, T,, range from 300 to 4500 K using the bowing-~ter~ow/~ngmuir probe technique. A detailed comparison of the electron attaching properties of CT0 with Cd0 is made. Thus, whilst electron capture to CeO occurs only in the p-wave channel at these I-,, it is tentatively reasoned that electron capture by CT0 proceeds preferentially in the s-wave channel below a T, of about 1000 K and in the p-wave channel and/or the s-wave channel al the higher r,.

A new experimental method has been developed for measurements of the rate constants of electron attachment as a function of the mean electron energy. The conventional pulse-radiolysis microwave-cavity method has been modified by applying the microwave heating technique to elevate the mean electron e
