New measurement of the 238U decay constant with inductively coupled plasma mass spectrometry
The 238 U decay constant ( λ U-238 ) is fundamental to radioisotope-based chronometry in the Earth and planetary sciences, yet only a single published λ U-238 value (Jaffey et al. in Phys Rev C 4(5):1889–1906, 1971 ) is widely applied. We have determined λ U-238 via the novel approach of measuring o...

U decay constant (
λ
U-238
) is fundamental to radioisotope-based chronometry in the Earth and planetary sciences, yet only a single published
λ
U-238
value (Jaffey et al. in Phys Rev C 4(5):1889–1906,
1971
) is widely applied. We have determined
λ
U-238
via the novel approach of measuring of
234
Th ingrowth in high-purity
238
U solutions, using isotope dilution mass spectrometry (ID-MS). The
234
Th decay constant (
λ
Th-234
) was measured via decay counting with high-purity Ge (HPGe)
γ
detectors. Preliminary results for
λ
U-238
agree with the value determined by α-counting [
1
] within the elevated uncertainty of 0.462% (
k
= 2). Ongoing efforts to reproduce
λ
U-238
with reduced experimental uncertainties will inform future conclusions. |
