Nuclear Reaction Codes
Nuclear reactions can proceed via different reaction
mechanisms. So far, I have
worked on direct reactions and compound nucleus reactions. There are
three codes to work with:
I also have a variety of smaller codes (like parametrized nuclear
reaction networks) for different purposes.
This is a statistical model (Hauser-Feshbach theory) code based on the
code SMOKER by Thielemann et al. It describes compound nucleus
reactions
by averaging over resonances. There is an on-line
fast access database (with HTML and Java interfaces)
of a previous version with further references
and the on-line web version
NON-SMOKERweb
for directly running the code (for collaborators only). The speciality
of NON-SMOKERweb
is that it can be completely
controlled through
a nice web UI which even allows to introduce new functions describing
certain nuclear properties (e.g. optical potentials) without
recompilation of the code!
This is a code to calculate direct radiative capture reactions with
neutral
or charged particles. Different optical potentials (including
Saxon-Woods and folding potentials) are built in, arbitrary potentials
or wave functions can be supplied as input. Electromagnetic transitions
considered are E1,
E2, M1. Results obtained with this code have been published in various
journal articles.
This is a DWBA (Distorted Wave Born Approximation)
code to calculate direct transfer reactions in the
zero-range or finite-range approximation. Different optical potentials
(including Saxon-Woods and folding potentials) are built in, arbitrary
potentials or wave functions can be supplied as input.
Results obtained with this code have been published in various
journal articles.

Astrophysics codes
Modelling stellar evolution and explosive astrophysical events
(supernovae, X-ray bursters) requires sophisticated hydrodynamics
codes.
Our group is making use of several different codes for different
applications, partly developed or extended by ourselves. Among the
codes
are AGILE (general relativistic; Liebendörfer), KEPLER (1-D
multizone
hydro code; Woosley), TYCHO
(quiescent stellar burning, also 1-D; Arnett),
and a smoothed particle hydrodynamics (SPH) code
(Benz, Rosswog).
I also have a variety of parameterized reaction
network codes
for different purposes: using full networks or equilibrium conditions.
Those codes are used for studying primordial nucleosynthesis, explosive
burning phases of stars, the r-, s-, p-, and rp-processes.
Such codes are also implemented into the hydrodynamics stellar
evolution
codes in order to follow nucleosynthesis in detail.
