    The LA150N Library

    Released: 1996-07-25

    This 150-MeV neutron library designated LA150N was released in July 2000 and updated in May 2002. There are data tables for 42 isotopes in the library. Forty-one are based on T-16 work and extend to 150 MeV. These are all ENDF/B-VI Release 6 evaluations, with the exception of Si-28, Nb-93, Bi-209, Pb-208, and the Hg isotopes. These exceptions were either not submitted for ENDF/B-VI Release 6, or have undergone minor modifications since then. The 42nd isotope is Be-9, which extends to 100 MeV and is based on work performed in T-2.

    The modification in May 2002 update was made to Pb-208 to correct a small error in the original release. The ZAID for Pb-208 has been changed from 82208.24c to 82208.25c to differentiate from the earlier version.

    The isotopes and ZAIDs on LA150N are as follows:

    (all ZAIDs end in .24c except for Pb-208)
