| Zusammenfassung |
| The paper is devoted to particle acceleration in turbulent current sheet
(CS). Our results show that the mechanism of CS particle interaction with
electromagnetic turbulence can explain the formation of power law energy
distributions. We study the ratio between adiabatic acceleration of particles
in electric field in the presence of stationary turbulence and acceleration
due to electric field in the case of dynamic turbulence. The correlation
between average energy gained by particles and average particle residence
time in the vicinity of the neutral sheet is discussed. It is also
demonstrated that particle velocity distributions formed by
particle-turbulence interaction are similar in essence to the ones observed
near the far reconnection region in the Earth's magnetotail. |
