The Theory of Stellar Evolution and Nucleosyntesis
The structure and evolution of the stars is governed by the equations of hydrodynamics coupled to a nuclear reaction network and a detailed description of the relevant physics and chemist. In this work we present a simple and introductory description...

180Ta production in the classical s-process
The production and survival of the quasistable isomer 180Ta during the stellar nucleosynthesis has remained a matter of discussion for years. A careful analysis of the available experimental data and theoretical calculations enabled...

Indirect techniques in nuclear astrophysics ? Asymptotic Normalization Coefficient and Trojan Horse,
Owing to the presence of the Coulomb barrier at astrophysically relevant kinetic energies it is very difficult, or sometimes impossible, to measure astrophysical reaction rates in the laboratory. That is why different indirect techniques are being us...

Measurement of Ge-73(n, gamma) cross sections and implications for stellar nucleosynthesis
Ge-73(n, gamma) cross sections were measured at the neutron time-of-flight facility n_TOF at CERN up to neutron energies of 300 keV, providing for the first time experimental data above 8 keV. Results indicate that the stellar cross section ...

Review and new concepts for neutron-capture measurements of astrophysical interest
The idea of slow-neutron capture nucleosynthesis formulated in 1957 triggered the stellar temperature range (from few eV up to several hundred keV) for most to the assessment of new aspects of s-process nucleosynthesis and ...
