D421900100016 Evacuated stainless steel cells diameter 2 cm, length D421900100017 2.5 cm closed with 50 um Al windows were filled with D421900100018 highly enriched 131Xe gas 99.6% up to a pressure of D421900100019 0.9 bar. D421900100020 The cells were irradiated with proton beams of 200 nA D421900100021 intensity at 28, 24, 20, 15 and 12.5 MeV primary D421900100022 energies, obtained by changing the accelerator D421900100023 settings, at the external beam line of the CGR 560 D421900100024 cyclotron of Vrije Universiteit Brussel. D421900100025 The beam intensity was controlled to keep it constant D421900100026 within 10% during the irradiations. D421900100027 The produced Cs isotopes were washed out of the gas D421900100028 cells. D421900100029 Total maximal loss in the recovery of Cs radioisotopes D421900100030 was estimated to be around 3% with an uncertainty of D421900100031 2%.
