heal.abstract	This paper presents results on charm photoproduction in the energy interval 40 to 160 GeV, obtained from the high-statistics charm samples of the NA 14/2 experiment at CERN. We measure the charm cross-section, the distributions in x(F) and p(T)2 and various production ratios and charge asymmetries. The total non-diffractive open-charm cross-section per nucleon is measured to be sigma(gammaN-->ccXBAR) = 540 +/- 60 +/- 100 nb at [E(gamma)] = 100 GeV. We discuss the photoproduction of charm in terms of theoretical and phenomenological models. We compare the measured p(T)2 and x(F) distributions with first-order QCD calculations of photon-gluon fusion and obtain a value for the charm-quark mass of m(c) = 1.5(+0.2/-0.1) GeV/c2.	en
