Abstract Short pulse x-ray generation which is produced through Thomson scattering is of interest not only to the basic collision physics, but also used in various research fields. In this work, some theoretical results have been obtained on Thomson scattering between (16MeV) relativistic electron energy and laser pulse energy (2J) of pulse duration (10ns). The differential cross sections of Thomson scattering have been determined between 0.1c up to 0.99c electron energies through different x-ray emitting angles. A relation between the differential cross sections and incident electron energies is established at an x-ray emitting angle equal to zero. In addition, x-ray pulse length over different scattering angles Picosecond X-Ray Generation Through Thomson Scattering.
