  The r-process involves neutron-rich nuclei far off stability for which no
experimental cross sections are known. Therefore, one has to rely on theory
which might be prone to considerable uncertainties far off stability. To
investigate the impact of such uncertainties, nucleosynthesis in hot bubble
models followed completely from high-temperature NSE to low-temperature neutron
capture freeze-out were calculated with largely varied rates. Due to the
(n,gamma)-(gamma,n) equilibrium established at the onset of the r-process, only
late-time neutron captures are important which mainly modify the abundances
around the third r-process peak.
