| Abstract: | A compact resonance ionization mass spectrometer is presented. It is presently applied for sensitive and highly selective ultratrace determination of the long-lived radioisotope 41Ca for environmental, biological, and fundamental investigations. The development of coherent multistep resonance ionization enables the realization of experimental detection limits as low as106 atoms per sample and very high isotopic selectivity above 1012. This revised version was published online in August 2006 with corrections to the Cover Date. |
