Nuclear Overlap Calculation


A high energy collision between two nuclei can be considered as a collision between two groups of nucleons. The number of binary nucleon-nucleon collisions and the number of participating nucleons can be calculated for a given impact parameter using the formalism written down by Kari Eskola in Nucl. Phys. B 323(1989)37. I wrote a simple program to perform these calculations numerically.

This approach, by the way, is also known under the names of 'wounded nucleon model' and 'Glauber model' and was, as pointed out by Glauber in his talk in the Quark Matter 2005 conference in Budapest, introduced by Bialas, Bleszynski, and Czyz, Nucl. Phys. B111(1976)461.
  • code  (250 lines FORTRAN)
  • description of the code  (8 pages pdf)
  • Alternatively, you can run the whole thing interactively via web. Jens Elgeti, GSI summer student in 2001, implemented the web interface.
  • run the code via web interface
