3. NATURE OF PHYSICAL PROBLEM SOLVED

  FORMAT: ENDF/B file 23

NUMBER OF GROUPS: Point Cross Sections, energies 1 keV to 100 MeV.
  NUCLIDES: Z = 1-83, 86, 90, 92 and 94.

  ORIGIN: Lawrence Livermore Laboratory

  WEIGHTING SPECTRUM: none

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
The data are for use in general purpose gamma-ray transport codes.  The Lawrence Livermore Laboratory has a continuing program to evaluate photon cross section.
The data are given in units of (barns/atom) for energies 1 keV to 100 MeV and for elements Z = 1-83, 86, 90, 92 and 94. The MAT numbers are equal to the atomic numbers (Z).
     The following cross sections are tabulated

     MT cross section type
     ---------------------
     501 total
     502 coherent scattering
     504 incoherent scattering
     516 pair production (includes triplet)
     603 photoelectric

6. TYPICAL RUNNING TIME

To compile EDIT-23 and edit the entire library requires 1.5 minutes on the IBM 360/65.
NEA-DB executed the test case of EDIT-23 on IBM 3081 in 5 seconds.
