| Zusammenfassung |
| Observations of a continual erosion of the strahl and build up of
the halo with distance from the sun suggests that, at least in part,
the halo may be formed as a result of scattering of the strahl. This
hypothesis is supported in this paper by observation of intense scattering
of strahl electrons, which gives rise to a proto-halo electron population.
This population eventually merges into, or becomes the halo. The fact
that observations of intense scattering of the strahl are not common
implies that the formation of the halo may not be a continuous process,
but one that occurs, in part, in bursts in regions where the conditions
responsible for the scattering are optimum. |
