We analyze neutron monitor data of solar cosmic rays in order to obtain information about their sources. We use three methods for these data analysis. As result, we obtain a set of evidences for two separate solar cosmic rays sources that we call as prompt and delayed components. We attempt here to substantiate a two sources scenario for the generation of both components. For the prompt component source, we suggest regular acceleration in a neutral current sheet. For the delayed one, we propose acceleration by magnetosonic wave turbulence. ©1996 American Institute of Physics.
