The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. We calculate direct neutron capture on the even-even isotopes Sn124-145 and Pb208-238 with energy levels, masses, and nuclear density distributions taken from different nuclear-structure models. The utilized structure models are a Hartree-Fock-Bogoliubov model, a relativistic mean field theory, and a macroscopic-microscopic model based on the finite-range droplet model and a folded…

Neutron-induced astrophysical reaction rates for translead nuclei
Neutron-induced reaction rates, including fission and neutron capture, are calculated in the temperature range 10 8 ≤ T (K) ≤ 10 10 within the framework of the statistical model for targets with the
Direct neutron capture cross sections of Ni-62 in the s-process energy range
Direct neutron capture on Ni-62 is calculated in the DWBA and the Maxwellian averaged cross sections and astrophysical reaction rates in the energy range relevant for s-process nucleosynthesis are
Systematical law of (n, γ) reaction cross sections of even-even nuclei
We have derived a formula for the neutron radiative capture cross section in the framework of a statistical model approach to nuclear reactions. Based on this formula, new systematics are established
Nuclear structure studies at ISOLDE and their impact on the astrophysical r-process
The focus of the present review is the production of the heaviest elements in nature via the r-process. A correct understanding and modeling requires the knowledge of nuclear properties far from
