Hydrogen plays a significant role in the formation of nanodiamond, terminating diamond surfaces and removing sp 2 bonded atoms from the surface during CVD diamond growth. However, there are only a few calculations that simulate nanodiamond development directly, and even less that do so in a hydrogen-containing environment. Recently, nanoscale graphitic(More)
5 ~ n a separate experiment using a mixed pion-electron beam, we measured the efficiency of our shower dc-tector for counting pions of various energies. This information was used along with measured pion electro-production cross sections to predict in a llontc Carlo calculation the pion contamination. The Monte Carlo agreed with the magnet reversed(More)

The A dependence of TO photoproduction is found to be almost independent of energy in this range in contrast to vector-meson dominance predictions. The direct coupling of photons to vector mesons leads to the somewhat surprising result that pho-tons appear to be strongly absorbed in nuclear matter despite total photon-nucleon c r o s s s e c-tions which(More)
