The enlarged new absorption cross sections of J/psi by pi and rho were put
into the hadron and string cascade model, JPCIAE, and the J/psi suppression
factors in P-A, O-U, S-U and Ph-Ph minimum bias collisions at 200A GeV/c w
ere calculated with nuclear absorption mechanism only. The results seem to
indicate that, with new enlarged cross section it is still hard to change t
he aspect that nuclear absorption mechanism itself could not easily account
for the J/psi anomalous suppression in Pb-Pb collisions.
