• Evaluation of the 87Rb decay constant by age comparison against the U-Pb system (2011, methodology): “There is also growing evidence (Begemann et al., 2001; Krumrei et al., 2006) that λK is probably ~1–2% lower than the presently accepted value from Steiger and Jäger (1977), suggesting”
• Reassessing the uranium decay constants for geochronology using ID-TIMS U–Pb data (2006, methodology): “…study approach the precision of the decay constants and weighted means of equivalent populations are well within those errors, it is possible to validate the accuracy of the Jaffey et al. (1971) counting experiments empirically and quantitatively (Begemann et al., 2001; Mattinson, 1994a,b, 2000).”
• The age of Dar al Gani 476 and the differentiation history of the martian meteorites inferred from their radiogenic isotopic systematics (2003, methodology): “01402 Ga 1 (Begemann et al., 2001) is used in age calculations.”
• K-Ar and Ar-Ar Dating (2002, background): “where t is the time since closure, λ is the total decay of (40)K, and (λe + λ′e) is the partial decay constant for (40)Ar (Begemann et al. 2001) (Table 2).”

Note that, as pointed out by Begemann et al. (2001), many of the normalization studies (e.g., Patchett and Tatsumoto, 1980; Luck et al., 1980; Minster et al., 1982) used (207)Pb/(206)Pb (rather than (206)Pb/(238)U) ages as th”
