The influence of the choice of nuclear mass model used in the calculation of the astrophysical rates of neutron capture reactions using a statistical approach on the result of the nucleosynthesis process simulation has been studied. Four nuclear mass models (FRDM model, macro-microscopic WS+RBF model, microscopic HFB-24 model, and the method of local mass relations (LMR model)) are considered. Nuclear mass uncertainties significantly affect the cross sections and rates of radiative neutron capture. Reaction databases in the REACLIB format are constructed on the basis of the considered mass models. The yield of process products under standard conditions is calculated using the reaction databases in the REACLIB format. The use of the LMR model leads to a significant increase in the yield of heavy nuclei in the mass number range of . [ABSTRACT FROM AUTHOR]
