  • Process for producing .sup.52 manganese
    Patent number: 4201625
    Abstract: A target containing vanadium, either of natural isotopic constitution or enriched either with respect to .sup.50 vanadium or .sup.51 vanadium, is bombarded with .sup.3 helium of an energy of about 14 MeV producing .sup.52 manganese by nuclear reaction from both of these isotopes of vanadium. After a waiting period for the disappearance of short-lived intermediates, the target foil is dissolved in acid and the .sup.52 manganese is extracted with a solution of a hydroxychinolin in chloroform. The oxinate complex of .sup.52 manganese thus extracted can be used directly as a source of .sup.52 manganese in the preparation of compositions for radiochemical or radiopharaceutical purposes.
