Zusammenfassung: | An electron-positron plasma in thermal equilibrium within a uniform magnetic field is
studied using a classical trajectory Monte Carlo simulation. The cross-magnetic-field
single-particle diffusion coefficient is evaluated as a function of the magnetic field
strength and plasma temperature. The transport rate is found to increase by many orders of
magnitude as the plasma temperature is lowered, for a magnetic field strength of 1 T. The
sharp dependence on temperature is due to electrons and positrons becoming temporarily
correlated and drifting across the magnetic field before dissociating. |
