Benchmark cross sections for electron-impact total single ionization of helium

We establish the total single ionization cross section for electron-impact ionization of helium, to an accuracy of few per cent, from near threshold to 1 keV. This is done fully ab initio using the convergent close-coupling method without the often-used frozen-core approximation. We find excellent a...
