The isotope 176Lu undergoes β- decay to 176Hf with a long half-life. From a plot of 176Hf/177Hf (y-axis) versus 176Lu/177Hf (x-axis) for a suite of cogenetic (=related) meteorites, Patchett & Tatsumoto (1980) obtained a 10-point isochrons with a slope of 0.0934 and an initial 176Hf/177Hf ratio of 0.27973. The age of the meteorites is known to be 4550 Ma from independent Pb-Pb dating. Calculate the decay constant (λ) and half-life (t1/2) of 176Lu decay
