ELECTRON-ENERGY DEPENDENCE OF ELECTRON-ATTACHMENT TO C-C7F14, CH3I AND CH2BR2 STUDIED BY THE PULSE-RADIOLYSIS MICROWAVE-CAVITY TECHNIQUE COMBINED WITH MICROWAVE-HEATING

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 energy from thermal to about 1 eV. This technique has been applied to the electron attachment to c-C7F14, CH3I and CH2Br2 in Xe buffer gas. The results are discussed in comparison with existing data.
