Abstract: 
We study the production of c (c) over bar pairs in nuclear reactions at SPS energies within the covariant transport approach HSD. The production of c (c) over bar pairs is treated perturbatively employing experimental cross sections while the interactions of c (c) over bar pairs with baryons are included by conventional cascade-type two-body collisions. Adopting 6 mb for the c (c) over bar-baryon cross section the data on J/Psi suppression in p + A reactions are reproduced in line with calculations based on the Glauber model. Additionally the dissociation of the c (c) over bar pairs by strings is included in a purely geometrical way. We find good agreement with the experimental data from the NA38 and NA50 Collaborations with an estimate for the string radius of R-s approximate to 0.2-0.25 fm. (C) 1999 Elsevier Science B.V.
