CONTRIBUTION TO THE CYCLOTRON TARGETRY .4. MEASUREMENT OF F-18, NA-21, AND NE-23 PRODUCTION YIELDS IN DEUTERON INDUCED REACTION ON NEON GAS

The radionuclide F-18 is of considerable interest for biochemical and physiological studies using positron emission tomography (PET). Of all methods used for its production only two have found wide application since their yield is high enough and the chemical form of the is suita ble for fluorination of organic compounds. Proton irradiation of enric hed water using O-18(p,n)F-18 reaction and deuteron bombardment of gas eous neon Ne-20(d,alpha)F-18 process are the commonly used effective c yclotron production procedures. In our previous papers(1,2) the differ ent reactions and target parameters of the deuteron irradiation of neo n gas were reported. In the present work, the production yields for th e (d,alpha),(d,n) and (d,p) reactions were determined.
