%0 Journal Article %T Improved Empirical Parametrization of Fragmentation Cross Sections %A Klaus S¨ımmerer %J Physics %D 2012 %I arXiv %R 10.1103/PhysRevC.86.014601 %X A new version is proposed for the universal empirical formula, EPAX, which describes fragmentation cross sections in high-energy heavy-ion reactions. The new version, EPAX 3, can be shown to yield cross sections that are in better agreement with experimental data for the most neutron-rich fragments than the previous version. At the same time, the very good agreement of EPAX 2 with data on the neutron-deficient side has been largely maintained. Comparison with measured cross sections show that the bulk of the data is reproduced within a factor of about 2, for cross sections down to the pico-barn range. %U http://arxiv.org/abs/1205.5436v2
