One- and two-neutron capture reactions of light nuclei in nuclear astrophysics
H. Herndl, R. Hofinger, H. Oberhummer
We discuss models to calculate one- and two-neutron capture reactions on light nuclei. These are applied to calculate the reaction rates of 15N(n,gamma)16N, 16N(n,gamma)17}N and 4H…
Analysis of the thermal cross section of the capture reaction 13C(n,gamma)14C
H. Herndl, H. Oberhummer
We investigate the thermal cross section of the reaction 13C(n,gamma)14}C which takes place in the helium burning zones of red giant star as well as in the nucleosynthesis of Inhom…
Measurement and analysis of neutron capture reaction rates of light neutron-rich nuclei
P. Mohr, H. Beer, H. Herndl +1
Several neutron capture cross sections of light neutron-rich nuclei were measured in the astrophysically relevant energy region of 5 to 200 keV. The experimental data are compared…
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…
Nuclear Reactions of Astrophysical Interest Involving Light Nuclei
H. Oberhummer, W. Balogh, V. D. Efros +2
An introduction to nucleosynthesis, the creation of the elements in the big bang, in interstellar matter and in stars is given. The two--step process He(2n,)He and the r…
Spectroscopic Amplitudes for One--Nucleon Transfer Between 1p0f--Shell Nuclei
E. Kwa{ś}niewicz, H. Herndl, H. Oberhummer
Spectroscopic amplitudes are calculated for one--nucleon transfer between low--lying, normal--parity states of nuclei in the lower part of the 1pf--shell. Calculations are per…
