NOTE: Do not use RAPGAP versions 2.06/33 - 2.07/03. There were bugs for diffraction when using HERACLES mode together with IFULL=1. Old versions as fortran file (USE HERACLES 4.6): Old versions as car file (USE HERACLES 4.6):
  • list of updates and news for RAPGAP 2.08
  • Source code of HERACLES 4.6 for use in RAPGAP
  • Get BASES 5.1 directly from GRACE
  • BASES 5.1 from a local copy
  • Example Makefile

  • Please make sure that one the following files is included in the link step (rap.f):
  • Examples for compiler options
  • Example Main program
  • Get the ACTW data files to be used in RAPGAP since version 2.08/01
  • Manual RAPGAP 2.08 (PS file) (not yet for version 2.08/02)


  • Many thanks to all the people for suggestions and all the checks. Special thanks to G. Briskin, A. Mehta,
    J. Phillips, P. Thompson, P. Schilling, Y. Tsipolitis, H. Kowalski and F-P. Schilling.
