For the description of the production of nuclei with A≥80 in the process of neutron capture nucleosynthesis a dynamical kinetic model is developed. The calculated r‐process abundances were found to be strongly depended on the predictions of neutron‐rich nuclei properties. The role of the β‐delayed process—(β−, kn) kn=1–3 and (β−,f ) is analyzed. The model dependence of the age of the Galaxy TG is analyzed in the method of actinide isotope chronometric pairs. The TG value is calculated in the exponential model of galactic nucleosynthesis by Fowler with various conditions of the r‐process proceeding and with various prognosticated nuclear data differs greatly. To coordinate numerous abundance calculations it is necessary to include a sudden spike of nucleosynthesis in the cosmological model. |
