In both of these cases we assume that the incoming beam of neutrons or photons is \"twisted\" by having an azimuthal phase dependence, {\\it i.e.}, it carries an additional angular momentum along its direction of propagation. Taking a low-energy limit of these reactions, we derive relations between corresponding transition amplitudes and cross sections with plane-wave beams and twisted beams.
