Use of electron-capture data at short pulse intervals for study of electron-capture mechanisms

Abstract

Electron-capture data obtained at short pulse intervals (50–100 μsec) cn be used to determine electron-capture mechanisms. The response function has been derived and it differs considerably from that at steady-state conditions. The electron-capture doefficient can be defined from the response function and it is directly proportional to the pulse frequency. The derived response function is in agreement with the experimental concentration, temperature, and pulse interval dependence.The response is independent of pulse width providing short pulse widths (0.5–1.0 μsec) are used at intervals larger than 50 μsec. The electron-capture coefficient at short pulse intervals is lower than at long pulse intervals where steady-state conditions prevail. However, this is partially compensated by a greater standing current at short pulse intervals.
