Angle-resolved electron spectra in short-pulse two-color XUV plus IR photoionization of atoms

Spectra and angular distributions of photoelectrons from ionization of atoms by a combination of two short pulses in the XUV and IR range are theoretically considered. The transition from the streaking regime for ultrashort XUV pulses to the sideband formation for longer pulses is discussed. For photoelectrons of sufficiently high energy (a few hundreds of eV), the peculiarity of the angular distribution and the gross structure of the sidebands are investigated.
