英文摘要	The projected angular distribution and transverse momentum distribution of proton projectile fragments produced in 3.7A GeV O-16, 500A MeV Fe-56, and 1.7A GeV Kr-84 induced by different kinds of emulsion target (H, CNO, and AgBr) interactions are investigated. It is found that the projected angular distribution and transverse momentum distribution can be well represented by a single Gaussian distribution. Comparison of transverse momentum distribution with the Maxwell-Boltzmann distribution reveals that proton projectile fragments are emitted from a single-temperature emission source. The temperature is different for different colliding systems, and linearly depends on the target size.
