Abstract

We review the current status of the nuclear reaction rates needed to study nucleosynthesis in massive stars. Results for the calculated nucleosynthesis of all stable species from Hydrogen to Bismuth in a completely evolved 25 M_⊙ star of initial solar metallicity will be presented. Special emphasis will be paid to two particular reactions, ¹²C(α, γ)¹⁶O and ²²Ne(α, n)²⁵Mg, and their effect on the structure of the star and resultant nucleosynthesis. Both have been measured many times, but the present range of experimental uncertainty translates into remarkable sensitivity of the calculated nucleosynthesis.
