The dynamics of electron surfatron acceleration by electromagnetic waves in the space plasma depending on the particles' longitudal momentum

In this paper, the capture and surfatron acceleration of an electron by strong electromagnetic waves propagating in the space plasma across a weak external magnetic field are considered on basis of nonlinear numerical calculations. The calculations have been made for various values of the longitudinal (along the magnetic field) momentum of a particle. The initial phase is constant and longitudinal momentum varies from 1 to 200.
