Abstract :
We use a 2-D hybrid numerical simulation to study velocity-driven magnetic reconnection in low-beta plasmas. Our results show that Alfven waves can be produced in the process. Under their action newborn ions undergo pitch-angle scattering and assume a spherical shell distribution. A part of the ions are accelerated to a maximum energy of about 4(miV2A0/2). The acceleration lasts over a time scale of 100/Ωi, and is extremely rapid. The energy spectrum of the accelerated ions is a double power-law spectrum.
