Interactions of relativistic [Formula Presented] and [Formula Presented] nuclei in hydrogen: Isotopic production cross sections

Document Type


Publication Date



The interactions of [Formula Presented] projectile nuclei with energies of 361, 546, and 765 MeV/nucleon and [Formula Presented] nuclei with 352 MeV/nucleon, have been studied in a liquid-hydrogen target as part of a program to study interactions of relevance to the problem of cosmic-ray propagation in the interstellar medium. We have measured the cross sections for the production of isotopic fragments of the projectile nuclei in these interactions. The variations of these cross sections with mass, charge, and energy, are examined for insights into any systematic features of this type of fragmentation reaction that might aid predictions of other, unmeasured cross sections. These cross sections are also compared with the values derived from the most commonly used prediction techniques. It is suggested that these techniques could be improved by taking account of the systematic features identified here. © 1997 The American Physical Society.
