Currently there are two electron data libraries: EL and EL03. MCNP Version 4C or later is required to use the newest electron data library EL03. The library EL03 is further described in LA-UR-00-3581.
Note that all electron Data for a given material must come from the same library, i.e. either EL or EL03.
EL03 can be downloaded either as a zip file or as a compressed tarball
