Relativistic and Quantum Revisions of the Multisource Thermal Model in High-Energy Collisions

Figure 2

Proton momentum distributions in relativistic (nonquantum) ideal gas model (solid curves) and classical ideal gas model (dashed curves). The different curves are calculated by (2.6) and (2.1), respectively, and are given for four temperatures indicated in the figure. The solid curves in Figure 2 are the same as those in Figure 1.
