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 (t_1/2 = 100 yrs) and ⁴⁰Ca(α,γ)⁴⁴Ti (59 yrs) reactions are presented.
