title: Production of 166Ho through 164Dy(n, gamma)165Dy(n, gamma)166Dy(beta-)166Ho and separation of 166Ho.
abstract: After irradiation with thermal neutrons 164Dy produces 166Ho through the nuclear reaction: 164Dy(n, gamma) 165Dy(n, gamma) 166Dy beta- --> 166Ho. 166Ho has been separated from the bulk dysprosium target with the help of HPLC using Aminex A7 ion exchanger resin and alpha-hydroxyisobutyric acid (alpha-HIBA) as the mobile phase. The separation was quantitative and without any contamination from the dysprosium target. Method has also been developed to produce holmium free of alpha-HIBA ligands. Attempts have been made to produce no-carrier-added recoiled 166Ho and 165Dy in water.
