    • 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 ...
    • 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 ...
