3. NATURE OF PHYSICAL PROBLEM SOLVED
FORMAT: ANISN, DOT, MORSE
NUMBER OF GROUPS: The neutron energy range (15 MeV to thermal) is described by 104 groups. The gamma-ray energy range (10 MeV to 0.02 MeV) is described by 22 energy groups.
NUCLIDES: N, O, Al, H, K, Si, Ca, Na, C, and Fe.
ORIGIN: For all materials, except C and K, was the Defense Nuclear Agency Working Cross Section Library dated September 1972. The K and C data came from ENDF/B-3.
WEIGHTING SPECTRUM: For the neutrons 1/E in the fast range and Maxwellian (300 deg.K) in the thermal range. For the gamma-ray interaction a flat weighting function was used.

The DLC-27 library was generated for use in albedo studies of neutrons incident on various types of concrete. It is probably also suitable for neutrons, gamma-rays, or coupled neutron and secondary gamma-ray transport through concrete-like materials.It is a coupled set of neutron and gamma-ray cross sections for the elements N, O, Al, H, K, Si, Ca, Na, C, and Fe.
