Abstract
We consider the differential cross sections for (e,2e) at intermediate energies Ei=150 eV where the two electrons escape with substantially different velocities and coplanar with the incident direction. We decouple the total kinetic-energy operator into two parts by introducing a parameter. The triple differential cross sections for electron-impact ionization of atomic hydrogen at intermediate energies are read as two parts: the structure and scattering factor and the correlation factor by using two-potential formula. We study that the affects on the recoil peak the correlation factor and the incident angle bring.关键词
