Comparison of the angle-resolved photoelectron energy spectra of the QRS model and the semiclassical simulations as well as the experimental measurements of Sheehy et al .[ 27 ] for single ionization of He in a 120-fs pulse with a wavelength of 780 nm at the peak intensity of 8.0×1014 W/cm2 at angles of (a) 0°, (b) 20°, (c) 40°, and (d) 70°.
