概要

論文の詳細を見る
The introduction of resonance ionization using continuous wave narrowband lasers into mass spectrometry has lead to the successful development of an efficient technique for ultra trace atom determination with outstanding specifications regarding isobaric and isotopic selectivity. Due to these features this compact laser-based method is just becoming competitive to conventional ultra trace detection techniques like accelerator mass spectrometry or low level decay counting and gives access to a variety of demanding investigations. Starting from high resolution atomic spectroscopy on high lying Rydberg states or autoionizing levels, selective determination for a number of ultra trace istopes becomes feasible. Experimental prerequisites as well as a number of challenging applications concerning in particular 41Ca-determination for environmental, bio-medical as well as fundamental investigations are presented.
