摘要：

We study compression-driven magnetic reconnection in a relativistic electron-positron plasma. Making use of a 2.5-dimensional particle-in-cell code, we simulated compression of a magnetized plasma layer containing a current sheet within it. We found that the particle spectrum within the reconnecting sheet becomes nonthermal; it can be approximated by a power-law distribution with an index of -1 and an exponential cutoff.
