%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ZZ-VITAMIN-C/B is a data library containing 171 neutron, 36 gamma-ray group cross section data for fusion and LMFBR neutronics.
The weighting function for the neutron data consists of six regions: a Maxwellian thermal spectrum (300K) up to 0.125 eV, a 1/E  slowing down spectrum to 820.8 KeV, a fission spectum to 10.0 MeV, a 1/E spectrum to 12.57 MeV, a velocity exponential fusion peak to 15.57 MeV, and a 1/E spectrum to 17.333 MeV. The gamma cross sections are flat-weighted.
The Legendre expansion order is P3. Data are available in the form of a 171 neutron group AMPX interface, a 171 neutron 36 gamma-  ray production AMPX interface, and a 36 group gamma-ray interaction  AMPX interface. The neutron data are also available in CCCC format as ISOTXS neutron cross section and BRKOXS self-shielding factor standard interface files.
Data exists for 60 nuclides used in proposed fusion or fission/ fusion hybrid systems.

4. METHOD OF SOLUTION

The data has been computed from ENDF/B files using the program MINX. The Bondarenko method is employed to create  group dependent resonance self-shielding factors to account for temperature and dilution effects.
The fractional error tolerances were set to 0.5 percent, and 0.1 percent for integration.

7. UNUSUAL FEATURES OF THE PROGRAM

The AMPX and CCCC interface formats allow the user to perform self-shielding and group collapsing to format a problem dependent library for his own use.
