Alpha-clustering and the stellar nucleosynthesis of carbon
Oberhummer, H.; Krauss, H.; Grun, K.; Rauscher, T.; Abele, H.; Mohr, P.; Staudt, G. (1994-09)The astrophysical S-factor and reaction rates for the triple-alpha process are calculated in the direct-capture model. It is shown that the stellar carbon production is extremely sensitive to small variations in the N-N ... -
Analysis of Li-8(alpha, n)B-11 below the Coulomb barrier in the potential model
Rauscher, T.; Grun, K.; Krauss, H.; Oberhummer, H.; Kwasniewicz, E. (1992-04)The reaction Li-8(alpha, n)B-11 is of interest in inhomogeneous big bang nucleosynthesis. A distorted wave Born approximation calculation employing folding potentials is presented for energies below the Coulomb barrier. ... -
The astrophysical S-factor of the reaction Be-7(P,gamma)B-8 in the direct capture model
Krauss, H.; Grun, K.; Rauscher, T.; Oberhummer, H. (1993)The astrophysical S-factor for the reaction Be-7(p, gamma)B-8 up to an energy of 2 MeV (c.m.) and the capture cross section of Li-7(n, gamma)Li-8 up to 1 MeV (c.m.) are calculated using the Direct Capture model (DC). Both ... -
Calculation of the Astrophysical S-Factor and Reaction-Rate for L-8(ALPHA,N0)B-11
Rauscher, T.; Krauss, H.; Grun, K.; Oberhummer, H. (ADAM HILGER LTD, 1992) -
Calculation of the He-3(He-3, 2p)He-4 AND H-3(H-3, 2N)He-4 astrophysical S-factor at low energies
Winkler, S.; Krauss, H.; Grun, K.; Rauscher, T.; Oberhummer, H.; Abele, H.; Staudt, G. (1992-08)We have calculated the cross sections for the charge symmetric reactions He-3(He-3,2p)He-4 and He-3(He-3,2p)He-4 at sub-Coulomb energies in the potential model. Good agreement with the experimental data is obtained. The ...
