Experimental measurement of sizes of emission sources for deuterons and α particles in 16O- p collisions at 3.25A GeV/c

The partial inelasticity coefficients of baryon fragments of oxygen nuclei and pions were investigated and the full inelasticity coefficient was determined for the first time in 16Op collisions at 3.25 A GeV/c. The fraction of kinetic energy of incident proton in 16Op collisions at 3.25 A GeV/c spent on formation of all the baryon fragments and production of charged and neutral pions was found. The experimental results were compared with those obtained in other experiments at high energies. The experimental full inelasticity coefficient in 16Op collisions at 3.25 A GeV/c was reproduced well by calculations within the framework of Glauber model of multiple scatterings in hadron–nucleus collisions.
