half-life (t1/2) of 6.647 days by beta decay to form the stable Hafnium nuclide, 177Hf. The maximum beta energy for the decay of 177Lu to 177Hf is 0.497 MeV. The average beta energy is approximately 0.13 MeV. Also low gamma energy is emitted, for instance at … 176Lu/177Hf value of DM (Griffin et al., 2000) recalculated to the decay constant of Soderlund et al.

Solution data from two laboratories (Amsterdam and Münster) yield an average present day 176 Hf/ 177 Hf of 0.282000 ± 0.000005 (2σ weighted mean), which we recommend as a reference and nomination value for laser-ablation Hf isotope analyses. Cl imaging shows no visible banding or zonation for CL-active elements.

Nuclear binding energy is the energy required to split an atom’s nucleus into protons and neutrons. Mass defect is the difference between the predicted mass and the actual mass of an atom's nucleus. The binding energy of a system can appear as extra mass, which accounts for this difference.
