“…Unfortunately, no experimental data are available for p+ 40 Ca at 1 GeV. There is one experiment at 763 MeV by Chen et al [14], but the resulting cross sections [σ −1p = (54.7 ± 7.9) mb; σ −1n = (29.8 ± 6.4) mb] are in sensible disagreement with the cross sections measured by the same group at lower energies and with the values suggested by the systematics of Fig. 3.…”

“…It is clear that the model predictions are in the right ballpark for neutron removal, but they overestimate the proton-removal data by a factor that can be as large as 3-4 for heavy nuclei. Note that the experimental data are globally consistent, even though they have been collected in inverse-kinematics experiments [14][15][16][17][18][19][20][21] or by off-line gamma spectroscopy [3,[22][23][24].…”

Improving the description of proton-induced one-nucleon removal in intranuclear-cascade models

et al. 2015

It is a well-established fact that intranuclear-cascade models generally overestimate the cross sections for one-proton removal from heavy, stable nuclei by a high-energy proton beam, but they yield reasonable predictions for one-neutron removal from the same nuclei and for one-nucleon removal from light targets. We use simple shell-model calculations to investigate the reasons for this deficiency. We find that a refined description of the neutron skin and of the energy density in the nuclear surface is crucial for the aforementioned observables, and that neither ingredient is sufficient if taken separately. As a by-product, the predictions for removal of several nucleons are also improved by the refined treatment.

“…In the present work, though we do not have data for 36 Ar, the 35 Cl data are available for comparison of different isospins, as it has T z = −1/2 while the two other beam ions both have T z = −2. When examining the odd-even effect in these data, we also consider other recently-published data of ours, using beams of 28 Si, and older data from Chen et al [9] for 40 Ca, to provide comparisons with T z = 0 projectiles.…”

Charge-changing and fragment production cross sections at 0• have been obtained for interactions of 290, 400, and 650 MeV/nucleon 40 Ar beams, 650 and 1000 MeV/nucleon 35 Cl beams, and a 1000 MeV/nucleon 48 Ti beam. Targets of C, CH2, Al, Cu, Sn, and Pb were used. Using standard analysis methods, we obtain fragment cross sections for charges as low as 8 for Cl and Ar beams, and as low as 10 for the Ti beam. Using data obtained with small-acceptance detectors, we report fragment production cross sections for charges as low as 5, corrected for acceptance using a simple model of fragment angular distributions. With the lower-charged fragment cross sections, we can compare the data to predictions from several models (including NUCFRG2, EPAX2, and PHITS) in a region largely unexplored in earlier work. As found in earlier work with other beams, NUCFRG2 and PHITS predictions agree reasonably well with the data for charge-changing cross sections, but do not accurately predict the fragment production cross sections. The cross sections for the lightest fragments demonstrate the inadequacy of several models in which the cross sections fall monotonically with the charge of the fragment. PHITS, despite not agreeing particularly well with the fragment production cross sections on average, nonetheless qualitatively reproduces some significant features of the data that are missing from the other models.

Processes involving few degrees of freedom in the frame of Intranuclear Cascade approaches

et al. 2016

Abstract. This article focuses on spallation reactions, i.e. interactions of energetic nucleons, basically with a kinetic energy in the 100 MeV to a few GeV range, with a target nucleus. These processes are described rather successfully by the so-called Intranuclear Cascade (INC) plus evaporation models. They can be viewed as a first stage of nucleon-nucleon collisions, ejecting fast particles, followed by evaporation of slow particles from the target remnant. These cascade + evaporation models have, now, globally reached a high level of predictive power, owing in particular to successive research programs. The present work, which is an outcome of one of these programs, the recent European Union ANDES research program, deals with a set of reactions (or observable quantities), which can be due to a single collision, such as the one-nucleon removal reactions or the quasi-elastic elastic process. A survey of the experimental data is presented, which allows to clearly point out that, often, the INC models are unsatisfactory for the description of these peculiar events, whereas they are rather successful for the rest of the experimental data. This paradoxical situation is tentatively related to quasi-particle effects which are neglected in INC models.
