D422100100018 The activity of the irradiated samples was measured D422100100019 nondestructively, without chemical separation. D422100100020 VUB: the samples were investigated three times: D422100100021 two measurements were performed shortly after end of D422100100022 bombardment and the third one was done a month later. D422100100023 CYRIC: each foil was placed onto the detector three D422100100024 times but the first measurements started one day after D422100100025 end of bombardment. D422100100026 The primary energy and the calculated energy D422100100027 degradation were corrected on the basis of the D422100100028 simultaneously re-measured excitation functions of the D422100100029 monitor reactions. D422100100030 The effect of the secondary neutrons was checked D422100100031 placing extra target foils at the end of the stack, D422100100032 exposed only to possible secondary neutrons. D422100100033 Recoil losses were estimated from recoil contamination D422100100034 of the adjacent Al monitor foils. D422100100035 Both effects were negligible in these measurements.
