Préparation de ¹⁴³Pr sans Entraineur par l'Echange d'Ion

Abstract

The 10 mC order ¹⁴³Pr was purified by the ion exchange following by the elimination of the most part of cerium as ceric phosphate precipitate. The purity of this source was examined and the yields of radioactive praseodymium were measured during the first precipitation, the reprecipitations and the ion exchange purification. Several remarks to obtain an extremely pure source was mentioned.
