Abstract
Accelerator Mass Spectrometry (AMS) is today the most selective and sensitive analytical techniques stellar-nucleosynthesis for determination of isotopic abundances ranging down to below 10-15. The principle and examples of the method are described. We now apply the technique to measurements of nuclear cross sections of stellar-nucleosynthesis reactions leading to long-lived nuclides. Recent measurements and experimental results for the important 62Ni(n,γ)63Ni (t1/2 = 100 yrs) and 40Ca(α,γ)44Ti (59 yrs) reactions are presented.
