摘要：

Electron-impact ionization of the ground state of helium is measured and calculated for the case of 64.6 eV incident electrons with coplanar outgoing 20 eV electrons. Various geometries are considered: symmetric, fixed theta(A) and fixed theta(B) - theta(A). The method of calculation is the convergent close-coupling theory. This theory is able to reproduce the angular profiles in essentially all of these geometries, yet it yields cross sections which are a constant factor of approximately two lower than experiment.
