  The transverse momentum distribution of produced charged particles is
investigated for gold-gold collisions at $\sqrt{s_{NN}}=200$ GeV. A simple
parameterization is suggested for the particle distribution based on the
nuclear stopping effect. The model can fit very well both the transverse
momentum distributions at different pseudo-rapidities and the pseudo-rapidity
distributions at different centralities. The ratio of rapidity distributions
for peripheral and central collisions is calculated and compared with the data.
