Abstract
We examine the production of open charm in antiproton annihilation
on finite nuclei. The enhancement of the subthreshold production
cross section, even in a nucleus as light as carbon, should provide a
clean signature of the reduction in the masses of these mesons
in-medium. We also show that a careful analysis of the D+ and
D- spectra can yield important information on the cross section
for 
scattering.
