Light Nuclides Observed in the Fission
نویسندگان
چکیده
Light nuclides produced in collisions of 1 A⋅GeV U with protons and titanium have been fully identified with a high-resolution forward magnetic spectrometer, the fragment separator (FRS), at GSI, and for each nuclide an extremely precise determination of the velocity has been performed. The so-obtained information on the velocity shows that the very asymmetric fission of uranium, in the U + p reaction, produces neutron-rich isotopes of elements down to around charge 10. New important features of the fragmentation of U, concerning the velocity and the N/Z-ratio of these light fragments, and a peculiar even-odd structure in N=Z nuclei, have also been observed.

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 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,...
متن کامل2003 review of neutron and non-neutron nuclear data.
This paper reviews the scientific literature for new measurements of both non-neutron and neutron nuclear data. Some of the highlights of this review are the following items. There was a withdrawal of a previous claim for discovery of element 118. There have been new measurements of some isotopic abundance values that have led to changes for many elements. There was a new set of recommended sta...
متن کاملSaturation Condition and Evolution of the Nuclides for Sub-critical System Driven by Accelerator
At present work, under initial inventory with Th and U, the evolution of nuclides in subcritical devices under given thermal, fast, hardening fast and fission neutron field are studied without the detail structure of sub-critical device and the burn-up being considered. It is supposed that the subcritical reactor consists of uniform in which the flux of neutron is homogeneous. The fissile nucli...
متن کاملPart II: First-chance fission
The results of model calculations on nuclide yields produced by firstchance fission of excited U nuclei are presented. The calculations show the washing out of structural effects (even-odd structure and fission channels), the broadening of the mass distribution and the reduction of the neutron excess with increasing excitation energy. The calculations are relevant for the design of future secon...
