Radiocarbon Dating Using Electrostatic Accelerators: Negative Ions Provide the Key
Abstract
Mass spectrometric methods have long been suggested as ways of measuring 14C/12C ratios for carbon dating. One problem has been to distinguish between 14N and 14C. With negative ions and a tandem electrostatic accelerator, the 14N background is virtually absent and fewer than three 14C atoms in 1016 atoms of 12 C have been easily measured.
