Direct observations by Kosmos-5 and other satellite sources indicate that the final radius of the plasma cloud accompanying the American high- altitude burst of 9 July 1962 did not exceed 600 km. This is less than the final radius for a plasma cloud expanding in a vacuum, which indicates considerable dissipation of energy. Particle ejection beyond the plasma cloud is assumed to be the reason for this discrepancy and three mechanisms are proposed to explain the ejection 1 diamagnetic ejection of plasma blobs due to instability at the interface between plasma and field 2 free separation in the magnetosphere of fission fragments neutralized in the beginning stages of cloud expansion, i.e., before the stage of inertial separation 3 free separation in the magnetosphere of fragments neutralized by charge exchange between ions in the plasma cloud and neutral particles in the atmosphere.
