(1.36 ± 0.07) × 106 y |
(2007NI16): Characterization of the ICN sediment 10Be/9Be composition. Reanalysis of the (1993MI26) ICN sediment and determination of the lifetime. | |
(1.53 ± 5%) × 106 y | (1993MI26): Analysis of NIST-4325: Excluded due to potential systematic error in characterizing the 10Be content (see notes). | |
(1.48 ± 5%) × 106 y | (1993MI26): Analysis of ICN sediment: Excluded due to potential systematic error in characterizing the 10Be content (see notes). | |
(1.34 ± 0.07) × 106 y | (1986HOZB) | |
(1.51 ± 0.06) × 106 y |
(1987HO27): Excluded because systematic errors surround the characterization of the ORNL-A and ORNL-Master 10Be solutions (see notes). See also (1988FAZX), Ins. Phys. Conf. Ser. No 94, section 11, 1988, 379. | |
(1.48 ± 0.15) × 106 y | (1975MA54): Discussion in (1987HO27) | |
(1.6 ± 0.2) × 106 y | (1972EM01): Update of (1947HU03) using more up-to-date cross section data. Excluded since sizeable systematic uncertainties are open. | |
(1.7 ± 0.4) × 106 y | (1972MC26): Correction to (1972MC26) by converting from mean lifetime to half-life. Excluded since sizeable systematic uncertainties are open. | |
(1.5 ± 0.3) × 106 y | (1972YI01) | |
(2.5 ± 0.5) × 106 y | (1947MC01): Superseded with (ln 2) correction factor in (1972MC26). | |
(2.9 ± 0.5) × 106 y | (1947HU03): Superseded with updated cross section data in (1972EM01). See also (1949HU19). | |
Other Reviews: | (1.387 ± 0.012) × 106 y | Average result obtained in (2010CH18 and 2010KO19). Used in most applied 10Be decay dating communities and AMS calibration applications. |
