Barzakh, G. Lhersonneau, L. Batist, D. Fedorov, V. Ivanov, K. Mezilev, P. Molkanov, F. Moroz, S. Orlov, V. Panteleev, Yu. Volkov, O. Alyakrinskiy, M. Barbui, L. Stroe, L. Tecchio] The diffusion-effusion model has been used to analyse the release and yields of Fr and Cs isotopes from uranium carbide targets of very different thicknesses (6.3 and 148 g/cm2) bombarded by a 1 GeV proton beam. Release curves of several isotopes of the same element and production efficiency versus decay half-life are well fitted with the same set of parameters. Comparison of efficiencies for neutron-rich and neutron-deficient Cs isotopes enables separation of the contributions from the primary (p + 238U) and secondary (n + 238U) reactions to the production of neutron-rich Cs isotopes. A rather simple calculation of the neutron contribution describes these data fairly well. The FLUKA code describes the primary and secondary-reaction contributions to the Cs isotopes production efficiencies for different targets quite well.
