How abundant is lutetium
WebLutetium-177 has a half-life of 6.647 days. Lutetium-177 decays by β-emission to stable hafnium-177 with the most abundant β-(79.3%) having a maximum energy of 0.497 MeV. The average beta energy is approximately 0.13 MeV. Low gamma energy is also emitted, for instance at 113 keV (6.2%) and 208 keV (11%). WebThe isotopes of lutetium range in mass number from 149 to 184. The primary decay mode before the most abundant stable isotope, 175 Lu, is electron capture (with some alpha and positron emission ), and the primary mode after is beta emission. The primary decay products before 175 Lu are isotopes of ytterbium and the primary products after are ...
