Abstract
A special probe has been used to detect ions reflected from a collisionless shock wave propagating perpendicular to the field in a magnetized, low- plasma. Reflected ions are observed only above a critical Alfvén number , and their orbits coincide with the familiar "foot" on the magnetic structure of supercritical shocks. We discuss the origin of the reflected ions.
