“…PHITS uses a cross section model developed by Tripathi to determine interaction probabilities, the Jaeri Quantum Molecular Dynamics (JQMD) model to describe nucleus-nucleus collisions, and the Generalized Evaporation Model (GEM) to model fission and evaporation processes. Several previous comparisons between our data and PHITS can be found in the literature [9,10,22,[30][31][32].…”

We report fragmentation cross sections measured at 0 • for beams of 14 N, 16 O, 20 Ne, and 24 Mg ions, at energies ranging from 290 MeV/nucleon to 1000 MeV/nucleon. Beams were incident on targets of C, CH2, Al, Cu, Sn, and Pb, with the C and CH2 target data used to obtain hydrogentarget cross sections. Using methods established in earlier work, cross sections obtained with both large-acceptance and small-acceptance detectors are extracted from the data and when necessary corrected for acceptance effects. The large-acceptance data yield cross sections for fragments with charges approximately half of the beam charge and above, with minimal corrections. Cross sections for lighter fragments are obtained from small-acceptance spectra, with more significant, modeldependent corrections that account for the fragment angular distributions. Results for both chargechanging and fragment production cross sections are compared to the predictions of the Los Alamos version of the Quark Gluon String Model (LAQGSM) as well as the NUCFRG2 and PHITS models. For all beams and targets, cross sections for fragments as light as He are compared to the models. Estimates of multiplicity-weighted helium production cross sections are obtained from the data and compared to PHITS and LAQGSM predictions. Summary statistics show that the level of agreement between data and predictions is slightly better for PHITS than for either NUCFRG2 or LAQGSM.

“…Additional complications arising in the interpretation of small-acceptance spectra are discussed elsewhere [22]. It was noted in that article that, at least for one simulated data set (650 MeV/nucleon 40 Ar), some 80% of He fragments were produced in association with heavier fragments.…”
