Abstract
The rate of expansion of the phase coordinate for a harmonically drive n pendulum is considered. The mean-squared displacement is found to gr ow as a linear function of time during chaotic motion, indicating dete rministic diffusion. The diffusion coefficient can be significantly in fluenced by the proximity of a window containing a periodic solution. We find that diffusion associated with intermittent chaos can be descr ibed in terms of an interleaving of the diffusion properties of the se parate modes taking part in the intermittency.
