Electron and recoil-ion momenta in single ionization of He by protons

For single ionization of He atoms in collisions with fast protons we have measured and calculated, as a function of the scattering of the proton, differential reaction cross sections and mean values of the He+ recoil momentum projected onto the transverse direction defined by the collision plane and...
