Photodisintegration of the alpha particle

Abstract

Abstract The cross section for the two particle, 4He(γ, P)3H, photodisintegration of the alpha particle is calculated, taking into account the interaction between the proton and triton in the final state. It is shown that this is insufficient to remove the discrepancy between the experimental crow section, and cross sections calculated with wave functions that are consistent with the binding energy of the alpha particle, even when the tensor force is included in the two body interaction.
