Spectroscopic factors for bound s-wave states derived from neutron scattering lengths
P. Mohr, H. Herndl, H. Oberhummer
A simple and model-independent method is described to derive neutron single-particle spectroscopic factors of bound s-wave states in nuclei from neutron…
The ^{144}Sm-αoptical potential at astrophysically relevant energies derived from ^{144}Sm(α,α)^{144}Sm elastic scattering
P. Mohr, T. Rauscher, H. Oberhummer +5
For the determination of the optical potential we measured the angular distribution of scattering at the energy with high ac…
Astrophysically Relevant Neutron Capture near the Border of Stability
P. Mohr, H. Oberhummer, H. Beer
The neutron capture cross section on Mg was measured in the astrophysically relevant energy region from 25 keV to 220 keV. The experimental results agree well with a calcula…
Reaction Rates of neutron capture by Li- and Be-isotopes
H. Herndl, R. Hofinger, P. Mohr +3
Neutron capture by neutron-rich Li- and Be-isotopes plays a role in big--bang nucleosynthesis, especially in its inhomogeneous version and in the --process occurring in supernov…
Measurement of direct neutron capture by neutron-rich sulfur isotopes
H. Beer, C. Coceva, R. Hofinger +4
Thermal neutron capture cross sections for S(n,)S and S(n,)S have been measured and spectroscopic factors of the final states have been extracted.…
Uncertainties In Direct Neutron Capture Calculations Due To Nuclear Structure Models
T. Rauscher, K. -L. Kratz, H. Oberhummer +3
The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. For spherical nuclei close to the dripline the statistical model (Hau…
Neutron-induced nucleosynthesis
H. Oberhummer, H. Herndl, T. Rauscher +1
Neutron--induced nucleosynthesis plays an important role in astrophysical scenarios like in primordial nucleosynthesis in the early universe, in the s--process occurring in Red Gia…
Measurement of neutron capture on Ca at thermal and thermonuclear energies
H. Beer, C. Coceva, P. V. Sedyshev +5
At the Karlsruhe pulsed 3.75\,MV Van de Graaff accelerator the thermonuclear Ca(n,)Ca(8.72\,min) cross section was measured by the fast cyclic activation technique…
Nuclear halo effects in neutron-capture reactions of astrophysical interest
H. Oberhummer, H. Herndl, R. Hofinger +1
The halo effect in the final states of astrophysically relevant direct neutron--capture reactions by neutron--rich nuclei is discussed. As an example, we calculate the cross sectio…
Ground--state energies and widths of He and Li
V. D. Efros, H. Oberhummer
We extract energies and widths of the ground states of He and Li from recent single--level R--matrix fits to the spectra of the H)He and the He$({\r…
Reaction rate for two--neutron capture by He
V. D. Efros, W. Balogh, H. Herndl +2
Recent investigations suggest that the neutrino--heated hot bubble between the nascent neutron star and the overlying stellar mantle of a type--II supernova may be the site of the…
