National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Abstract Thick-target neutron yields and energy spectra from (alpha,n) reactions in honogeneous media calculated with ORIGEN-S and SOURCES were compared. SOURCES calculates yields and spectra from fundamental physics and data and is applicable to any combination of alpha-particle slowing-down, emitting, and target elements. ORIGEN-S employs approximations for both its UO2 and borosilicate-glass options that limit its applicability. Yields from both ORIGEN-S options compare favorably with yields from SOURCES. For UO2-like slowing down media, spectra using the UO2 option compare moderately well with SOURCE spectra. ORIGEN-S with the borosilicate-glass option is often employed for any non-UO2-like slowing down media to generate spectra, but any agreement with SOURCES spectra is conincidental.
