Nucleosynthesis of heavy elements in the accretion disk. The steady-state model is calculated for an accretion rate of Ṁ = 1.0 M⊙ s-1 and a black hole spin a = 0.9. Top panel: abundance distribution of free protons and neutrons (dashed lines) as well as helium, and most abundant isotopes of nickel, iron and cobalt. Bottom panel: distribution of the most abundant isotopes of argonium, titatnium, cuprum, and zinc.
