Documentation on the T16_2003 Libraries

Released: 2003-07-25

T16_2003 is a continuous-energy neutron data library compatible with MCNP versions 4C and later. It is based on the 2003 evaluations from the Nuclear Physics group T16 at LANL and includes data for 15 target isotopes. Data are provided for

• ³H,

• ^232-241U,

• ²³⁷Np,

• ²³⁹Pu,

• ²⁴¹Am, and ²⁴³Am.

Room-temperature tables have been created for each of the 15 isotopes (ZAID endings of .69c), tables at 3000 K have been created for each isotope except ³H and ²³⁷Np (ZAID endings of .68c), and 77 K tables have been created for ²³⁵U, ²³⁸U, and ²³⁹Pu (ZAID endings of .67c).
