Radioactive Isotopes of the Rare Earth Elements, III. Lutecium Isotopes and Hafnium Isotopes,

Abstract

A study has been made of radioactive isotopes of lutecium and hafnium, produced by bombardments of thulium and ytterbium with 38, 31, and 19 Mev alpha-particles, of lutecium and hafnium with 19 Mev deuterons, and of tantalum with 190 Mev deuterons. The techniques of bombardments, chemical separations, measurement of radio- activities, etc., used have been described previously. These have now been applied to a study of radioactive isotopes of lutecium, and, since the interpretation of data has depended upon the characterization of lutecium daughters of hafnium parents, also of radioactive isotopes of hafnium. The present knowledge of radioactive isotopes of these elements is given in Table I. p3,4
