  An analysis of the energy spectra of protons emitted in reactions of 47 MeV/u
projectiles with Sn and Au targets provides evidence for high momentum tails in
the intrinsic momenta spectra of the projectiles. These high momentum spectra
decrease with wavenumber $k$ at a rate proportional to $1/k^4$. We suggest that
additional experiments could provide a more refined value for the value of the
power law exponent.
