✦ Synopsis
With the inverse kinematics method, the reaction mechanism which leads to the formation of light nuclides was investigated with a 1 A GeV 238 U beam impinging on a liquid H 2 target. Isotopes of all elements with Z 6 were unambiguously identified, and the velocity of every produced nuclide was measured with great precision. Results show that very asymmetric fission of uranium nuclei produces neutron-rich isotopes of elements down to around charge 10. When uranium interacts with heavier nuclei the features of the reaction change drastically: while fission is the main mechanism for the production of light masses in 1 A GeV 238 U on H 2 , projectile fragmentation plays a dominant role in 1 A GeV 238 U on Ti leading to the formation of stable or neutron-deficient isotopes of all elements.
