We use a dry extraction method to obtain trapped C02 of shallow ice cores from a blue ice area of East Antarctica. In-situ-produced 14C extracted in 14CO2 and 10CO concentrations show a mean ratio of 3.4 ± 0.4. Correction for insitu 14CO2 resulted i

Shallow ice cores from an Antarctic blue-ice area at Scharllenbergbotncn were 14C-analyzed using a dry-extraction technique and accelerator mass spectrometry. The in situ production was determined from the 14CO component and used to deduce the natura

A dry extraction method of CO2 included in glacier ice adds a contamination equivalent to 1.8 μg modern carbon for a 35 μg C sample. This enables radiocarbon dating by accelerator mass spectrometry of 35 μg C samples to about 25 000 BP. Measured 1

The distribution of giant quadrupole resonance strength in 24,26Mg obtained from inelastic α- and proton-scattering experiments and α-capture experiments have now been shown to be compatible. The results show that the giant quadrupole resonance str
