A measurement of charge of ultra-relativistic projectile fragments (1 Ł Z Ł 3) obtained in ¹⁶O-emulsion interaction at 60 A GeV/c has beee made. Li-projectile fragments were identified from the charge distribution of the projectile fragments. The transverse momentum distribution of the Li projectile fragments (Z = 3) was studied. The data were compared with Maxwell-Boltzmann distribution and they revealed the existence of a single temperature. The results are compared with other data on ultra-relativistic nuclear collisions.
