The single-particle orbits due to a large amplitude, backward propagating electromagnetic wave and an axial guide magnetic field are derived, and the stability of the orbits is discussed. The large amplitude electromagnetic wave acts like a magnetostatic wiggler in a free-electron laser. Two classes of orbit are found corresponding to ..cap omega../sub 0/ < ..gamma..(..omega.. /SUB w/ + k /SUB w/ v) and ..cap omega../sub 0/ > ..gamma..(..omega.. /SUB w/ + k /SUB w/ v), where ..cap omega../sub 0/ is the electron cyclotron frequency, ..omega.. /SUB w/ and k /SUB w/ are the frequency and wave vector of the electromagnetic wave, ..gamma.. is the relativistic factor, and v is the axial electron velocity. However, unlike the case of a magnetostatic wiggler, both classes of orbit are shown to be stable.
