The production of xenon isotopes with protons of energies from 320 to 590 MeV

Cross sections for the production of 121Xe, 122Xe, 123Xe, 125Xe and 127Xe were measured from protons of energy 320-590 MeV impinging on relatively thin (0.171-0.707 g/cm2) targets of CsCl, BaC03 and La203. Yields of radioactive I and Te were calculated for protons of 540 MeV based on the collection of the Xe gases after a cyclotron bombardment time of 3 h with a processing time of 1 h vs breeding time. The practicality of producing 123I with high energy protons is discussed. Ratios of the main contaminents (125I and 121Te) 24 h after the Xe extraction were calculated vs breeding time using the above parameters. Also discussed is the possibility of the production of 127Xe with this method. (author)
