摘要
Relativistic momentum and energy equations of electrons in an intense laser field are derived with Hamilton-Jacobi equation.For initial electrons in non-equilibrium or Maxwellian equilibrium distributions in preplasmas,suprathermal electron energy distributions are obtained analytically and numerically.The calculation results agree well with the experiments.
