ABSTRACT The radiocarbon ( 14 C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision decay counting, it is now possible to efficiently produce large datasets annual resolution purposes using small amounts wood. intercomparison on single-year tree-ring samples presented here first investigate specifically offsets between AMS laboratories at high precision. results show that are capable measuring Holocene age with an accuracy and comparable or even goes beyond what though they require thousand times less It also shows not all always consistent their stated uncertainties. long-term benefits studies this kind more accurate measurements with, in future, better quantified
