The motion of charged particles is studied numerically and analytically using a test particle approach. Acceleration near the X‐type neutral line is described in terms of adiabatic invariants and separatrix crossings. The relation between regular and chaotic properties of the process is discussed for a realistic source in the plasma mantle.
