We study the influence of nuclear mass formulae as well as β-decay models on the r-abundance distribution resulting from canonical calculations of the nucleosynthesis r-process. This analysis is performed considering a single astrophysical event, or a more realistic superposition of events. We discuss conditions of validity of the waiting point approximation, propose an explanation of the smoothness of the r-elements abundance curve, and show that no unique fit to the observed r-abundance profile can be extracted.
