Abstract

Off-axis final states which develop from initially unstable, but cylindrically symmetric, 2D vorticity distributions were investigated. Experiments with electrons demonstrated that such states result when the initial vorticity distribution is close to the boundary. A simple thermodynamic model, maximizing the entropy of a state consisting of a diffuse background was described. A simple off-axis equilibrium model that assumes that a fraction of the initial circulation evolves into a coherent vortex was also described.
