Abstract
CHROMIUM hydroxide (Cr(OH)3) was subjected to the action of slow neutrons produced by the cyclotron of the Collège de France and was then transformed into the sulphate by dilute sulphuric acid. Potassium dichromate was added to this solution of the sulphate so as to obtain an equimolecular system of Cr+++ and ½ Cr2O7--. After a time which varied from 15 to 120 minutes, the chromic salt was precipitated by boiling with ammonium hydroxide and the dichromate as the barium salt.
