It has been used to count individual {sup 85}Kr and {sup 81}Kr atoms present in a natural krypton sample with isotopic abundances in the range of 10{sup {minus}11} and 10{sup {minus}13}, respectively. The atom counts are free of contamination from other isotopes, elements,or molecules. The method is applicable to other trace-isotopes that can be efficiently captured with a magneto-optical trap, and has a broad range of potential applications.","","INIS; OSTI as DE00755891","Argonne National Lab., IL (US)","US Department of Energy (US)","","United States","2000-05-25T00:00:00Z","English","Conference","","Conference: 17th International Conference on Atomic Physics, Florence (IT), 06/04/2000--06/10/2000; Other Information: PBD: 25 May 2000","","Medium: P; Size: 18 pages","","ANL/PHY/CP-101981","W-31109-ENG-38","TRN: US0003791","","","2008-02-05T00:00:00Z","755891","https://www.osti.gov/biblio/755891","https://www.osti.gov/servlets/purl/755891","","",""
