Measurements and computational analysis of the natural decay of ¹⁷⁶Lu

RADIOACTIVITY ¹⁷⁶Lu(β^-), (EC); measured Eγ, Iγ, X-rays, self-scintillation spectra of Lu-containing crystal, Eβ, Iβ, βγ-coin; shape of the β-spectrum Eβ, experimental shape factor, ¹⁷⁶Lu β endpoint energy, branching ratios for the β-decay to 6⁺ and 8⁺ of ¹⁷⁶Hf, Q-values, upper limit for the EC-decay branch. ¹⁷⁶Lu(β^-); calculated σpectrum Eβ, logft values. ¹⁷⁶Yb(2β^-); deduced Q-values. Q-values area based on the measured cyclotron frequencies published in this paper. Spectra measurements performed with lutetium-containing scintillator crystals (LuAG:Pr and LSO:Ce) surrounded by NaI(Tl) and CeBr₃ spectrometers.

ATOMIC MASSES ¹⁷⁶Lu, ¹⁷⁶Hf, ¹⁷⁶Yb; measured cyclotron frequencies ratios for combinations of ¹⁷⁶Lu, ¹⁷⁶Hf and ¹⁷⁶Yb ions among themselves; deduced mass excess for ¹⁷⁶Lu and ¹⁷⁶Hf based on the known values for ¹⁷⁶Yb and measured ratios. Comparison to AME2020 and other experimental data. Penning trap mass spectrometry (PTMS) at Low Energy Beam and Ion Trap (LEBIT) facility at the National Superconducting Cyclotron Laboratory (NSCL).
