    Atom-trap trace analysis of 41Ca/Ca down to the 10–17 level

    The cosmogenic isotope 41Ca with a half-life of 99,000 years can, in principle, serve as a tracer for environmental processes at an age scale beyond the reach of 14C. With accelerator mass spectrometry, the ratio...

    Ferromagnetic origin of Na and Mn codoped CaZn2As2 diluted magnetic semiconductor: A first-principles study

    We have investigated the electronic structure and magnetic properties of Na and Mn codoped CaZn2As2 using density functional theory within the generalized gradient approximation (GGA)+U schemes. We have shown tha...

    Analysis of 85Kr: a comparison at the 10-14 level using micro-liter samples

    The isotopic abundance of 85Kr in the atmosphere, currently at the level of 10−11, has increased by orders of magnitude since the dawn of nuclear age. With a half-life of 10.76 years, 85Kr is of great interest as...

    Atom trap trace analysis

    A new method of ultrasensitive isotope trace analysis has been developed. This method, based on the technique of laser manipulation of neutral atoms, has been used to count individual 85Kr and 81Kr atoms present ...
