Nuclear reactions induced in silver by 25.2 GeV 12C ions have been studied by the activation technique and compared with those induced by 300 GeV protons.

Two sets of data were normalized to each other by requiring that the weighted mean of 15 cross section ratios for products in A = 66 - 90 region be equal to unity. SIG(C=PROTON) stands for the reacion with proton beam (PLAB=300 GeV) with the same final state.

Enhanced production of NA-24 by wide angle secondaries produced in the interaction of relativistic carbon ion with copper

Radiochemical activation techniques were used to study the behavior of projectile fragments formed in the interaction of 44 GeV C12 ions within thick Cu targets. After a short review of the results obtained hitherto with this Cu-target technique, the interaction of 44 GeV C12 with several copper target configurations yielding the deep spallation product Na24 is described. Energetic fragments which are emitted into the laboratory angles 10°≤θ≤45° appear to produce more Na24 (up to nearly one order of magnitude) than calculated with a phenomenological model and an intranuclear cascade model. This enhanced production of Na24 by wide-angle secondaries is only observed for 44 GeV C12 on copper, but not for 25 GeV C12 on copper. Some normalization experiments with 4 GeV He4 and 2.6 GeV p are described.

NUCLEAR REACTIONS OF TANTALUM WITH 3.65-A/GeV C-12 IONS AND 3.65-GeV PROTONS

J.Phys.G 17 (1991) 675-690, 1991.
Inspire Record 281499 DOI 10.17182/hepdata.38565

The cross sections of a number of target residues formed in the reactions of 3.65 A GeV 12C ions and 3.65 GeV protons with tantalum have been measured. The measurements have been done by direct counting of irradiated targets with a Ge(Li) gamma-ray spectrometer. Charge dispersions and mass-yield distributions were deduced from these data. The results are discussed in terms of the basic concepts of high-energy nuclear physics. They are also compared with intranuclear cascade and abrasion-ablation model calculations.

Recoil properties of deep spallation and fragmentation products in the interaction of tantalum with 3.65-A-Gev C-12 ions and protons

Phys.Scripta 43 (1991) 133-136, 1991.
Inspire Record 299297 DOI 10.17182/hepdata.39412

Thick-target recoil properties of deep spallation and fragmentation products of the interaction of tantalum with 3.65 AGeV 12C-ions and 3.65 GeV protons have been studied. The kinematic parameters such as mean product kinetic energies and velocities of the remnant have been deduced from the data by means of the two-step vector velocity model of high-energy reactions. The results have also been used to test the applicability of the factorization hypothesis to the kinematic properties.

Momentum transfer in the reactions of 13.6-GeV/nucleon O-16 with copper

Mean ranges and forward-to-backward ratios have been determined by the thick-target, thick-catcher technique for fragments from the interaction of 13.6-GeV/nucleon O16 with copper. Experimental data are analyzed in terms of a two-step model and results are discussed in the context of limiting fragmentation and factorization and the predictions of a simple model for momentum transfer. Momenta imparted in the initial interactions of 13.6-GeV/nucleon O16 were inferred to be ∼12% lower than those for fragmentation of Cu by high-energy protons.

Nuclear reactions induced by 3·65 A GeV12C-ions and 3·65 GeV protons on target elements55Mn,59Co,nat Ni andnatCu were investigated by using the foil stack activation technique and Ge(Li) gamma-ray spectroscopy. Charge dispersions and mass-yield distributions of radioactive residues were obtained from the parametrization of measured spallation cross sections. Discussion of results from this and other radiochemical reactions of high-energy protons and12C-ions with complex nuclei is presented in terms of the concepts of limiting fragmentation and factorization.
