O159800100013 COMMENT *By authors*.Before starting the irradiation, the O159800100014 target vessel was evacuated. Two traps close to the O159800100015 target are mounted in the exhaust tubing system to O159800100016 capture the rest of F-18 activity in gaseous phase O159800100017 carried away with the neon gas. After irradiation all O159800100018 originated activity was measured to calculate the totalO159800100019 balance of the products. Immediately after the EOB the O159800100020 gas phase passed through the first trap containing ion O159800100021 exchanger papers for adsorption of Ne-21 and then O159800100022 passed into the evacuated second trap to catch the O159800100023 Ne-23. The measurement of the foil was repeated after O159800100024 several hours to eliminate the influence of short livedO159800100025 co-produced activities, which can originate in the O159800100026 inserted foil due to fast neutrons. O159800100027 *By authors*.In addition to the desired radionuclide O159800100028 F-18, there are three other radionuclides co-produced O159800100029 in the same system:Na-21 via Ne-20(d,n)Na-21(22.5 sec)O159800100030 and Ne-23 via Ne-22(d,p)Ne-23(37.6 sec) reactions. O159800100031 A very low activity of Na-22(2.602 year) may be O159800100032 observed by the measurement after the decay of the O159800100033 F-18. This activity originates presumably via the O159800100034 Ne-22(d,2n)Na-22 and via Ne-21(d,n)Na-22 reactions. O159800100035 DETECTOR (GELI) a semiconductor gamma-X-rays spectrometer with O159800100036 Ge(Li) detector and the combination of two ionization O159800100037 chambers were used. the detector efficiency in O159800100038 dependence on the detected photon energy was O159800100039 established by means of gamma-etalons.
