    • Astrophysical and nuclear physics aspects of the r-process 

      Thielemann, Friedrich-Karl; Freiburghaus, C.; Rauscher, T.; Kratz, K.L.; Pfeiffer, B.; Cowan, J.J. (World Scientific Publishing, 1998)
      The formation of elements as heavy as Th and U and beyond is due to the rapid neutron-capture process (r-process), which causes the production of highly unstable nuclei near the neutron drip-line and functions via neutron ...

    • The astrophysical r-process : A comparison of calculations following adiabatic expansion with classical calculations based on neutron densities and temperatures 

      Freiburghaus, C.; Rembges, J.F.; Rauscher, T.; Kolbe, E.; Thielemann, Friedrich-Karl; Kratz, K.L.; Pfeiffer, B.; Cowan, J.J. (1999-05-01)
      The rapid neutron-capture process (r-process) encounters unstable nuclei far from beta-stability. Therefore its observable features, like the abundances, witness (still uncertain) nuclear structure as well as the conditions ...

    • Explosive nucleosynthesis and the astrophysical r-process 

      Thielemann, Friedrich-Karl; Freiburghaus, C.; Rauscher, T.; Kolbe, E.; Pfeiffer, B.; Kratz, K.L.; Cowan, J.J. (American Institute of Physics (AIP), 1998)
      We give an overview of chemical equilibria in explosive burning and the role which neutron and/or proton separation energies play. We focus then on the rapid neutron-capture process (r-process) which encounters unstable ...

    • Production of heavy-elements in inhomogeneous cosmologies 

      Rauscher, T.; Applegate, J.H.; Cowan, J.J.; Thielemann, F.K.; Wiescher, M. (1994-07-10)
      Baryon density inhomogeneities during big bang nucleosynthesis can result from a variety of possible causes (e.g., quantum chromodynamic and electroweak phase transitions; cosmic strings). We present here the consequences ...

    • The r-process in supernovae 

      Thielemann, Friedrich-Karl; Argast, D.; Mocelj, D.; Rauscher, T.; Cowan, J.J.; Kratz, K.L.; Pfeiffer, B. (World Scientific Publishing, 2004-09)
      This introductory review aims at understanding r-process nucleosynthesis by addressing the issues involved, nuclear properties, necessary environment conditions, properties of different suggested r-process sites, observational ...
