The conduction band tail electron resonance was observed at 2 K in a-Si:H by time-resolved optically detected magnetic resonance experiments, using intense pulsed excitation. The exchange interaction between the tail electrons and the trapped holes at A centres was elucidated by the observation of shift of the A centre g-value with delay time of the microwave pulse after pulsed excitation. Dynamical processes of radiative and nonradiative recombination are discussed on the basis of the experimental results,
