It is shown under very general assumptions that at small momentum transfers ..delta.. (..delta..approximately-less-than1/R, where R is the deuteron radius) considerable cancellation takes place between the following nonadiabatic effects: 1) effects associated with the motion of the nucleons (recoil in the elementary scattering events) cancel against the contribution from processes in which the incident particle is successively scattered from different nucleons, which are rescattered from one another in the meantime; and 2) effects due to the change in amplitude for the elementary event on moving off the energy shell cancel against the contribution from processes in which the incident particle is successively scattered by a single nucleon, which interacts with the other deuteron nucleon in the meantime. This situation obtains both at high energies, and at medium and low energies, and helps to explain the success and wide range of applicability of the widely used theories of multiple scattering based on the idea of fixed (rigidly connected) nucleons. Such cancellation also shows how dangerous it can be to attempt ''to improve partially'' simple theories.
