摘要：

An exact Sagdeev equation for arbitrary-amplitude solitary kinetic Alfvén waves in a non-thermal plasma is derived. For small β′, the proportion of fast electrons, an analytical expression for the exact pseudopotential V(φ) is obtained. For several values of β′, the Sagdeev potential V(φ) has been calculated by integrating the Sagdeev equation. It is found that, depending on the values of β′, both hump and dip solitons exist.
