Summary

The usual theory of whistler propagation, in which the effects of electrons alone are considered, leads to the conclusion that whistler ray directions cannot differ markedly from the direction of the geomagnetic field. When the effects of heavy ions are considered, however, it is found that all directions of propagation are possible at audio frequencies, and that the dispersion of frequencies takes place in opposite senses for longitudinal and transverse propagation. These theoretical results may suggest new possibilities for the detection of heavy ions and for the interpretation of some types of audio-frequency observations.
