B012400100013 Irradiations of a Few Minutes to Two Hours were CarriedB012400100014 Out with Deuterons of Incident Energies of 50 and 90 B012400100015 MeV, Respectively. Beam Currents Ranged Between 5 and B012400100016 10 Nanoampere. B012400100017 SAMPLE Stack Consisting of Up to 40 Nabr-Pellets, Thickness B012400100018 Between 60 and 150 Mg/Cm**2, Encapsulated in B012400100019 Polyethylene Foils of 7 Mg/Cm**2. For Beam Monitoring, B012400100020 Al-Foils of 50 Micrometers were Inserted at Different B012400100021 Positions in the Stack. A Total of 5 Stacks were B012400100022 Irradiated.
