چکیده
Spallation residues and fission fragments from 1A GeV 238U projectiles irradiating a liquid hydrogen target were investigated by using the fragment separator at GSI for magnetic selection of reaction products including ray-tracing, energy-loss and time-of-flight techniques. The longitudinal-momentum spectra of identified fragments were analyzed, and evaporation residues and fission fragments could be separated. For 1385 nuclides, production cross sections down to values of 10 microb with a mean accuracy of 15%, velocities in the uranium rest frame and kinetic energies were determined. In the reaction all elements from uranium to nitrogen were found, each with a large number of isotopes.

Measurement of nuclide cross - sections of spallation residues in 1 A GeV 238 U + proton collisions
The production of heavy nuclides from the spallation-evaporation reaction of U induced by 1 GeV protons was studied in inverse kinematics. The evaporation residues from tungsten to uranium were identified in-flight in mass and atomic number. Their production cross-sections and their momentum distributions were determined. The data are compared with empirical systematics. A comparison with previ...
متن کاملModel predictions of the fission - product yields for 238 U Part IV : Selected case studies
The results of model calculations on nuclide yields produced in selected scenarios using reactions with U nuclei are presented. The calculation combines the modelling of the initial reaction mechanism, the deexcitation process including the fission competition with the prediction of the nuclide production in the fission of excited U and all daughter nuclei produced in the evaporation cascade. T...
متن کاملA model for consecutive spallation and fragmentation reactions in inverse kinematics at relativistic energies
Secondary reactions induced by relativistic beams in inverse kinematics in a thick target are relevant in several fields of experimental physics and technology, like secondary radioactive beams, production of exotic nuclei close to the proton drip line, and cross-section measurements for applications of spallation reactions for energy production and incineration of nuclear wastes. A general mat...

Thin targets of 238U were bombarded with 45, 55, 65 and 69 MeV protons at the Cyclotron and Radioisotope Center (CYRIC) of Tohoku University in Japan. Gamma rays emitted from the fission products were recorded and analyzed by using gamma spectroscopy. Then, the cross sections for the formation of fission products, fragment mass distributions, and total fission cross sections were measured. Spec...
متن کاملCrossover from a fission-evaporation scenario towards multifragmentation in spallation reactions
Mostly for the purpose of applications for the energy and the environment and for the design of sources of neutrons or exotic nuclides, intense research has been dedicated to spallation, induced by protons or light projectiles at incident energies of around 1 GeV. In this energy range, while multifragmentation has still a minor share in the total reaction cross section, it was observed to have,...
