摘要

Around 270 medium-mass residual nuclei, formed in spallation reactions induced by Xe-136 projectiles impinging on a liquid hydrogen target at 500 A MeV, have been unambiguously identified at GSI using the magnetic spectrometer FRS. The individual production cross sections and the longitudinal momentum distributions have been determined with high accuracy. These data represent an important constraint for theoretical models describing spallation reactions. (C) 2013 Elsevier B.V. All rights reserved.
