摘要

The variation of effective cross section in Maxwellian neutron distributions with temperatures in the range -195 degrees C to 20 degrees C have been measured for Usup(233), Usup(235), and Pusup(239) fission, and for Usup(238), Thsup(232), Cusup(63), Insup(115), Lusup(176), and Ausup(197) capture. Foil activation methods were used. Mnsup(55), which has known 1/v dependence, was used as the reference. The results, with some from previous measurements covering temperatures from 20 degrees C to 300 degrees C, are compared with suitable integrations of ENDF/B-V data. Except for Lusup(176) and Ausup(197) the results agree within the estimated uncertainties with the ENDF/B-V data. (Atomindex citation 17:081300)
