ENDF/B-VI, Release 6
--------------------
The twelfth distribution of the ENDF/B-VI data tapes was released in September 1999. The distribution includes no completely new evaluations, but major updates for 36 other evaluations in the neutron sublibrary (mainly extending to 150 MeV) and 29 new evaluations in the proton sublibrary.
These updates have now been processed at the NEA and the new release is available for online searches and for complete download. Please note there are only a relatively small number of changes (as given below) along with a link to the new tape. All other sublibraries remain unchanged from Release 5 and are shown at the bottom of the page.
