Neutron Capture Cross Sections for the Weak s Process
M. Heil, A. Juseviciute, F. Kaeppeler +3
In past decades a lot of progress has been made towards understanding the main s-process component that takes place in thermally pulsing Asymptotic Giant Branch (AGB) stars. During…
Time scales of the s process - from minutes to ages
F. Käppeler, S. Bisterzo, R. Gallino +7
A discussion of the time scales in the s process appears to be an approriate aspect to discuss at the occasion of 70th anniversary of Roberto Gallino, the more as this subject has…
The 14C(n,g) cross section between 10 keV and 1 MeV
R. Reifarth, M. Heil, C. Forssen +14
The neutron capture cross section of 14C is of relevance for several nucleosynthesis scenarios such as inhomogeneous Big Bang models, neutron induced CNO cycles, and neutrino drive…
Opportunities for Nuclear Astrophysics at FRANZ
R. Reifarth, L. P. Chau, M. Heil +6
The "Frankfurter Neutronenquelle am Stern-Gerlach-Zentrum" (FRANZ), which is currently under development, will be the strongest neutron source in the astrophysically interesting en…
Solving the stellar 62Ni problem with AMS
I. Dillmann, T. Faestermann, G. Korschinek +11
An accurate knowledge of the neutron capture cross sections of 62,63Ni is crucial since both isotopes take key positions which affect the whole reaction flow in the weak s process…
Asymptotic Giant Branch models at very low metallicity
S. Cristallo, L. Piersanti, O. Straniero +3
In this paper we present the evolution of a low mass model (initial mass M=1.5 Msun) with a very low metal content (Z=5x10^{-5}, equivalent to [Fe/H]=-2.44). We find that, at the b…
