Abstract

The potential of the ²⁶Al isotope for exposure and burial dating applications has not been fully realized to date due to the low efficiency for producing the Al^- ion in negative ion sources. Here, we show that it is possible to use the AlO^- ion instead, which is produced an order of magnitude more efficiently, provided that a gas-filled magnet is employed to reduce the intense flux of ²⁶Mg ions at the detector. It is then possible to achieve comparable counting statistics for ²⁶Al as for the much more widely used ¹⁰Be.
