REACTION AND FISSION CROSS-SECTIONS OF 750 A-CENTER-DOT-MEV U-238 IONS ON PB, CU AND AL-TARGETS

Charge-loss and fission cross-sections of U-238 at 750 A . MeV were me asured on Al, Cu and Pb targets. The charge-loss rate was obtained by the attenuation method. Fission was selected by detecting the pair of highly ionizing fragments. Since the neutron-loss cross sections were measured in a parallel experiment for the same projectiles, all cross sections contributing to U-238 collisions on nuclei are available now as function of the target mass number and can be compared with current models.
