Magnetic sublevel population in 1s-2p excitation of helium by fast electrons and protons
TL;DR: In this article, experimental and theoretical results for the magnetic sublevel population of the helium atom in collisions with fast (vi = 3-9 au) electrons and protons are reported, and the particle-antiparticle Z± difference exceeds the statistical error of measurement up to collision velocities vi≈6 au for excitation of sublevels with M = 0.
