POSITRONIUM FORMATION IN HELIUM
Journal Article

· Proc. Phys. Soc. (London)
The positronium formation cross section in a positron collision with a normal He atom is calculated by Born's approximation for positron energies up to 125 ev. As judged by the size of the maximum cross sections obtained at positron energy of 27 ev, the coupling between elastic scattering and positronium formation is far from weak. This coupling suggests that virtual formation of positronium may play an important part in the elastic scattering of slow positrons by He atoms. The coupled equations for this effect are derived.
