Reverse Beta Decay

I've been thinking about the scenario of reverse beta decay for some time now. Normal beta decay follows: n -> p + e + v. Under most circumstances, that happens spontaneously because it is a lower energy configuration. From what I've read, in dying stars that are about to become neutron stars, the reverse reaction is energetically favored. So the question is, can beta decay be reversed under experimental conditions at moderate energies? I have no idea what the energy requirements are, so I'm a little in the dark. I read somewhere that theoretically you don't even need the neutrino in the reverse reaction. This is because colliding a proton and electron could produce both a neutron and an electron neutrino by way of the conservation of the lepton number. It would end up being p + e -> n + ev.
