Abstract
The data of J/psi suppression at large x(F) in pA collisions are used to in fer the existence of gluon depletion as the projectile proton traverses the nucleus. The modification of the gluon distribution is studied by use of a convolution equation whose nonperturbative splitting function is determine d phenomenologically. The depletion factor at x(1) = 0.8 is found to be abo ut 25% at A = 100.
