TWO-ELECTRON ATOMS IN SHORT INTENSE LASER PULSES

摘要: We discuss a method of solving the time-dependent Schrodinger equation for atoms with two active electrons in strong laser field, which we used previous paper [A. Scrinzi and B. Piraux, Phys. Rev. A 56, R13 (1997)] to calculate ionization, double excitation, harmonic generation helium by shea pulses. The employs complex scaling an expansion explicitly correlated basis. Convergence calculations is documented error estimates are provided. results He at peak intensities up 10(15) W/cm(2) wavelength 248 nm accurate least 10%.
