Polarization of Light from Collision of a Proton Beam with Helium Atoms

Abstract
We have measured the relative cross-sections and the polarization of the light resulting from the excitation of helium by a proton beam for the following transitions: 3D12P1(λ=6678 Å), 3S12P1(λ=7281 Å), 3D32P3(λ=5876 Å), 3S32P3(λ=7065 Å).
