Classical and Quantal Scattering. I. The Classical Action

摘要: Classical scattering is based on the action A = S − S0, where over actual trajectory and S0 equivalent without interaction. For two‐body spherical potential Δ(L, E) LΘ, Θ deflection angle Δ classical phase, limit of 2ℏδl (E). new, rapidly convergent integral expression given for (L, E). From this derived a expansion in 1/E valid fixed L≠O, an form 1/L E. The lowest term agrees with Massey Mohr, higher terms are evaluated.
