Scientists use a laser based magneto-optical trap to date 500 000 year old Egyptian groundwater. However, the low abundance and solubility of 81 Kr in water have presented a significant challenge to ...

A laser based magneto-optical trap that captures isotopes of krypton (Kr) gas can date samples of water and ice that are up to 1 million years old. Developed by a team of researchers in the US and ...
