Show affiliationsHollow Li2+(2s) production in a collision between a fast electron and a neutral lithium target is studied theoretically by a procedure which determines the fully-differential cross section of the corresponding (e, 3e) process. The calculated cross sections are obtained within the framework of the first Born approximation. The two slow emitted electrons in the continuum are described by the fully correlated three Coulomb interactions (3C). The results are compared to those of the double ionization of lithium resulting in a residual Li2+(1s). The comparison between these two channels is essential to get precious indication of the different mechanisms in double ionization of a three-electron target and to observe directly electronic correlation, which is the main cause of the double ionization by fast electron impact.
