摘要：

Ne+ to Ne8+ ionization yields in 10(14) W/cm(2) to 10(18) W/cm(2) laser fields are reported over a 10(9) dynamic range. A 3D relativistic rescattering model incorporating (e,2e) and (e,3e) electron impact ionization, single- and double-excitation is compared to the data. For double ionization the agreement is excellent; however, for higher charge states the model accounts for only 15% of multielectron nonsequential ionization. Rescattering is not affected by the laser magnetic field until 10(17) W/cm(2).
