LA RAPIDEZ DE DISTRIBUCIÓN DE PROTONES EN COLISIONES NÚCLEO-NÚCLEO EN LAS ENERGÍAS DE SINCROTRON DE GRADIENTE ALTERNANTE (AGS) Y SINCROTRON DE SUPER PROTON (SPS) ES ANALIZADA USANDO EL MODELO DEL CILÍNDRO TERMALIZADO. LOS RESULTADOS CALCULADOS AL SER COMPARADOS CON LOS RESULTADOS EXPERIMENTALES ESTAN EN CONCORDANCIA CON LAS COLISIONES DE SI-AL Y SI-PB A 14:6 AGEV/C, PB-PB A 158 AGEV/C Y S-S A 200 AGEV/C.AbstractTHE PROTON RAPIDITY DISTRIBUTIONS IN NUCLEUS-NUCLEUS COLLISIONS AT THE ALTERNATING GRADIENT SYNCHROTRON (AGS) AND THE SUPER PROTON SYNCHROTRON (SPS) ENERGIES ARE ANALYZED BY THE REVISED THERMALIZED CYLINDER MODEL. THE CALCULATED RESULTS ARE COMPARED AND FOUND TO BE IN AGREEMENT WITH THE EXPERIMENTAL DATA OF SI-AL AND SI-PB COLLISIONS AT 14:6 AGEV/C, PB-PB COLLISIONS AT 158 AGEV/C, AND S-S COLLISIONS AT 200 AGEV/C.THE PROTON RAPIDITY DISTRIBUTIONS IN NUCLEUS-NUCLEUS COLLISIONS AT THE ALTERNATING GRADIENT SYNCHROTRON (AGS) AND THE SUPER PROTON SYNCHROTRON (SPS) ENERGIES ARE ANALYZED BY THE REVISED THERMALIZED CYLINDER MODEL.
