Title: Photofission cross-section ratio measurement of 235U/238U using monoenergetic photons in the energy range of 9.0–16.6 MeV

Abstract

Photofission cross-section ratios of 235U and 238U have been measured in this paper using monoenergetic photon beams at the HIγS facility of TUNL. These measurements have been performed in small energy steps between 9.0 and 16.6 MeV using a dual-fission ionization chamber. Measured cross-section ratios are compared with the previous experimental data as well as with the recent evaluated nuclear data library ENDF.
