Strong-field photoionization of helium

Not Accessible

Your library or personal account may give you access


This study examines the photoelectron spectra (PES), the electron angular distributions, and the ion yields of helium in an intense laser field of 1014–1016 W/cm2. The strong-field double ionization of helium is measured over 12 orders of magnitude and is compared with a classical two-electron ionization model.
