Abstract
Using data taken by SELEX during the 1996--1997 fixed target run at Fermilab, we study the production of charmed hadrons on copper and carbon targets with [summation over (term)] .sup.-, p, [pi] .sup.-, and [pi] .sup.+ beams. Parametrizing the dependence of the inclusive production cross section on the atomic number A as A .sup.[alpha], we determine [alpha] for D .sup.+, D .sup.0, D .sub.s .sup.+ , D .sup.+(2010), I .sub.c .sup.+ , and their respective anti-particles, as a function of their transverse momentum p .sub.t and scaled longitudinal momentum x .sub.F. Within our statistics there is no dependence of [alpha] on x .sub.F for any charm species for the interval 0.1
