Abstract:
The transverse mass distributions of protons produced in Au-Au collisions at 8 A GeV and Pb-Pb collisions at 158 A GeV are calculated by using the Monte Carlo method in the framework of the multisource ideal gas model.It is found that our calculated results are in agreement with the experimental data in nucleus nucleus collisions at high energies.
