Experimental Cross Sections And Velocities Of Light Nuclides Produced In The Proton-Induced Fission Of U At 1 GeV
Light nuclides produced in collisions of 1 A GeV U with hydrogen have been observed with a high-resolution forward magnetic spectrometer, the fragment separator (FRS), at GSI. Fragments were identified in A and Z and their production cross-sections measured. For each nuclide the velocity was precisely determined from the measured magnetic rigidity. This insight into the kinematics of the relati...
متن کاملProduction of light nuclides in 1 GeV proton-induced fission of U
A dedicated experimental program, devoted to reaching a full comprehension of the proton-induced spallation reactions, started in 1996 at the GSI. The accurate knowledge of these reactions is relevant both for the development of methods of incineration of radioactive waste [1] and for the production of secondary beams [2]. Within this program, the first ever complete survey on nuclide productio...
متن کاملMeasurement 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 کاملProduction of residual nuclides in the spallation of U
The accurate prediction of formation cross sections of isotopes produced in spallation and fission reactions at intermediate energies is of extreme importance for the design of ADS and radioactive-ion-beam facilities. The predictive power of the computational tools is determined by the description of the reaction mechanisms involved. The physics involved in such reactions is still a subject of ...
متن کاملMeasurement of a complete set of nuclides, cross sections, and kinetic energies in spallation of 238U 1A GeV with protons.
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 co...
