3. DESCRIPTION OF PROBLEM OR FUNCTION


%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

  FORMAT: LASL transport theory programs

  NUMBER OF GROUPS: 18-, 24-, and 25-group.

NUCLIDES: Al, B, Be, C, Cd, Cl, D, Ga, F-194, Fe, H, K, Li-6, Mo, Na, Ni, O, Pu-239, Pu-240, Pu-249, Th, U-233, U-235, U-238, and Zr.  
  ORIGIN: Los Alamos Scientific Laboratory _ Univ of California.

  WEIGHTING SPECTRUM:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Group constants and computed neutron cross sections are tabulated for a variety of materials including - Al, B, Be, C, Cd, Cl, D, Ga, F194, Fe, H, K, Li6, Mo, Na, Ni, O, Pu239, Pu240, Pu249, Th, U233, U235, U238, and Zr. These are presented as 18-, 24-, and 25-group calculations for reactors with neutron energies ranging from fast to thermal.

4. METHOD OF SOLUTION

The tables are arranged in increasing nuclide
number in the  format used by the LASL  transport theory programs.
With a few  exceptions, elements are given  in alphabetical order.
All cross sections are in barns.
