Absolute cross sections and thick target/thick catcher recoil properties have been determined for radionuclides produced in the reaction between copper and 86 MeV/A ~2C ions. Integration of the obtained mass yield curve gives a cross section of reactions leading to spallation products of 1,440 mb.The F/B-ratios are found to increase with decreasing product mass, reaching a maximum of ~ 100 for products with masses 20-25 mass units lower than the target mass, followed by a decrease. The recoil data have been analyzed with the two-step vector model to deduce momentum transfer and product kinetic energies. The momentum transferred to an intermediate system is found to increase for reactions leading to decreasing product masses, reaching values of 1/3 of full momentum transfer. The derived mean kinetic energies are found to be higher than found in comparable proton induced reactions. Some possible explanations for this phenomenon have been discussed. The results have been compared with Monte Carlo cascade-evaporation calculations, and the agreement between the predictions and experiment is in general found to be good.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
