High-intensity effects in electron scattering in the presence of non-markovian fluctuating fields

摘要: Abstract Within a non-markovian treatment of the phase fluctuations radiation field (phase diffusion model) and non-perturbative theory laser-assisted electron scattering, we show that in very intense fields tha lifetime particle energy states may be reduced to such an extent make invalid markovian approximation for field. It is due many real virtual multiphoton exchanges, occuring during collision event. Thus, range applicability appears restricted domain weak particle—field coupling.
