摘要:

The motion of an electron in a linearly polarized wiggler with an axial guide field is found to be nonintegrable. There is evidence for chaos from numerical calculations of Poincare´ maps and of nonzero Lyapunov exponents. Resonances can be predicted from a one‐dimensional Hamiltonian perturbed by a small ‘‘time‐dependent’’ quantity.
