【Abstract】 The fast expansion processes in a spherically symmetrical laser-plasma are investigated. The analytic expressions for the density, velocity and energy scaling law of fast ions under ambipolar acceleration are found. Explanations are given on various possible mechanisms which are responsible for the formation of the multipeaked distribution of ion kinetic energies.更多还原
