Emission probability of the 66.7 keV γ transition in the decay of ¹⁷¹Tm

RADIOACTIVITY ¹⁷¹Tm(β^-); measured Eγ, Iγ, photon emission probability of the 66.7-keV γ transition in ¹⁷¹Yb from ¹⁷¹Tm decay using ⁶⁰Co as a primary standard and ⁴⁴Ti/⁴⁴Sc in secular equilibrium as secondary standard, with measurements made for ¹⁷¹Tm decay using a combination γ-spectrometry and inductively coupled mass spectrometry (ICP-MS) techniques. Comparison with previous experimental values. Relevance to astrophysical interest as a branching point nucleus along the s-process path.
