Small recoil momenta double ionization of He and two-electron ions by high energy photons

Miron Ya. Amusia, Evgeny G. Drukarev, Evgeny Z. Liverts

We calculate various differential and double differential characteristics of ionization by a single photon for H${}^{-}$, He and for the two-electron ions with Z=3,4,5 in the region of…
