B, Atomic, molecular and optical physics}, month = {Aug}, note = {application/pdf, We investigated the Coulomb focusing effect on the space distribution of the rescattering electron wavepacket created in the laser–atom interaction solving the time integral equation. The Coulomb focusing is conspicuous in the even-number returns since the rescattering electron energies are lower there. The Coulomb force focuses the rescattering electron beam into a small space and the rescattering electron beam current intensity can reach the order of 1010 A cm−2, much more intense than the conventional electron beam used in scattering experiments. The Coulomb focusing effect plays a less important role for the first return and this explains why the released kinetic energy spectra have a peak at the third return in the experiments of the double ionization of H2 molecules.}, pages = {165603-1--165603-4}, title = {Coulomb focusing effect on the space distribution of the rescattering electron wavepacket in the laser–atom interaction}, volume = {42}, year = {2009} }
