Archaeological results from accelerator dating good country dating songs
Mass spectrometers detect atoms of specific elements according to their atomic weights.They, however, do not have the sensitivity to distinguish atomic isobars (atoms of different elements that have the same atomic weight, such as in the case of carbon 14 and nitrogen 14—the most common isotope of nitrogen).“It is another sobering example of cocked-up dates,” says Higham, whose laboratory is leading a revolution in radiocarbon dating.By developing techniques that strip ancient samples of impurities, he and his team have established more accurate ages for the remains from dozens of archaeological sites.

Then, in the twentieth century, carbon dating found the bones to be about 22,000 years old — even though much of Britain was encased in ice and seemingly uninhabitable for part of that time.
When Higham eventually got the bones, his team came up with a more likely scenario: they were closer to 33,000 years old and one of the earliest examples of ceremonial burial in Western Europe.
However, the reliability of phytolith radiocarbon dating has recently been questioned.
The development of a new extraction protocol for phytoliths, with paired dating between phytoliths and other materials from the same sediment, may provide further evidence for the reliability of phytolith dating.
