Investigation of fragment production for fragment charge numbers between one and eight versus the degree of excitation of the fragmenting nucleus in 16Op collisions at a momentum of 3.25 GeV/c per nucleon

New experimental data on the mean-multiplicity distribution of fragments whose charge number ranges between one and eight and on the distribution of the mean kinetic energy of few-nucleon fragments (A = 1–3) are presented versus the 4-momentum transfer from the target proton to the oxygen nucleus in ¹⁶Op collisions at a momentum of 3.25 GeV/c per nucleon. These data are systematically compared with the predictions of the cascade-fragmentation-evaporation model.
