✦ Synopsis

The non-linear saturation of whistler mode instability in the solar wind is considered here. The resulting heating and acceleration are calculated. It is shown that this instability heats predominantly the a-particles and the ratio of heating rates of a-particles to ions have been calculated. This instability is shown to be effective in accelerating c~-particles than ions. However, this process cannot account for v,,/ v~ >_ l.

There exists a discrepancy between theory and observations regarding the velocity ratio of a-particles and ions in the solar wind. The observations (

The existence of a long-term variation, related to the solar activity, of the average a-particle abundance in the solar wind has been suggested by Robbins et al. (1970) and recently confirmed by Bollea et al. (1972) andOgilvie (1972). Hirshberg et al. (1972b), comparing the distribution of the a-par
