    MCNP Photoatomic Data Libraries - MCLIB03

    Released: 2002-07-25

    There are four photon transport libraries maintained by X-5 and distributed with MCNP: MCPLIB, MCPLIB02, MCPLIB03 and MCPLIB04.

    MCPLIB03 [1] was officially released in 2002 as another extension of the MCPLIB/MCPLIB02 data set. The cross section, form factor and fluorescence data on MCPLIB02 and MCPLIB03 are identical. MCPLIB03 includes the addition of the momentum profile (CDBD) data, derived from the work of Biggs, Mendelsohn & Mann [2].

    The MCPLIB63 and MCPLIB84 data libraries are new versions of the MCPLIB03 and MCPLIB04 data libraries where the probability of interacting with a given shell is stored using as a cumulative distribution function. MCPLIB63 and MCPLIB84 can be called using the library ID's .63c and .84c respectively. The choice of IDs is intended to keep these updates out of the general sequence of releases and indicate their special nature. It is highly recommended that users of MCNP5 download these updated libraries and replace their existing XSDIR file with a version that includes the MCPLIB63 and MCPLIB84 entries and does not include any reference to the MCPLIB03 and MCPLIB04 versions.
