  We study the lepton flavor violating process, $e+ T \to \tau +T'$, at a few
GeV. This process can be studied by experiments directing GeV scale electron or
positron beams on internal or fixed targets. We study the effects of some low
energy lepton flavor violating interactions on this process. We study the
sensitivities of this process on these low energy lepton flavor violating
interactions and compare them to the sensitivities of lepton flavor violating
$\tau$ decay processes. Comparing with $\tau$ decay processes, this process
provides another way to study the lepton flavor violating effects with $e-\tau$
conversion and it can be searched for in facilities with GeV scale electron or
positron beams which are available in a number of laboratories in the world.
