Can a neutron decay into a proton + muon (+ muon-neutrino)

Can a neutron, if it has enough kinetic energy, decay like:

$$\hspace{0.3cm} n \rightarrow p + \mu^- + \bar{\nu}_\mu$$

I assume it's not allowed since it's not on the possible decay modes on the Particle Data Group (http://pdg.lbl.gov/), but I don't know if they only account decays allowed from rest masses.
