The Atom Trap Trace Analysis (ATTA) apparatus in Heidelberg offers the unique ability to count the rare argon isotope 39Ar by addressing optical transitions in the atom by laser light of narrow line width. The counting method utilizes the high amount …
The 39Ar dating accuracy of the Atom Trap Trace Analysis experiment in Heidelberg is depending on the sample size and measuring time which can be reduced by increasing the current atmospheric 39Ar count rate. The collimator has great scope for …
