Abstract
A study has been made of neutron-deficient radioactive isotopes of lutetium and hafnium produced by bombardments of thulium and ytterbium with alpha-particles of various energies; of ytterbium with 10-Mev protons, and of lutetium with protons of energies from 10 to 70 Mev. Seven radioactive isotopes of lutetium and four of hafnium, all previously unreported, are described.
