Time Delay in Electron Collision with a Spherical Target as a Function of the Scattering Angle

We have studied the angular time delay in slow-electron elastic scattering by spherical targets as well average of electrons this process. It is demonstrated how connected to Eisenbud–Wigner–Smith (EWS) delay. The specific features both and energy dependencies these delays are discussed detail. potentialities derived general formulas illustrated numerical calculations slow potential fields absolutely hard-sphere delta-shell same radius. conducted studies shed more light on delays.
