Neutron multiplicity in the fission of 238U and 235U with neutrons up to 200 MeV.
T. Ethvignot,Matthew Devlin,H. Duarte,T. Granier,R. C. Haight,B. Morillon,R. O. Nelson,John M. O'Donnell,D. Rochman +8 more
TL;DR: It is reported that fissions induced by 200 MeV neutrons produces approximately 10 more prompt neutrons than fission induced by reactor neutrons.

Neutron-induced reaction studies at FIGARO using a spallation source
TL;DR: Fast Neutron-Induced Gamma-Ray Observer (FIGARO) as discussed by the authors is designed to study fast neutron-induced reactions that result in the emission of γ rays and neutrons.

C. Romano,Yaron Danon,Robert C. Haight,Stephen A. Wender,David J. Vieira,Evelyn M. Bond,Robert S. Rundberg,J. B. Wilhelmy,John M. O'Donnell,A. Michaudon,Todd Bredeweg,D. Rochman,T. Granier,T. Ethvignot +13 more
TL;DR: The LSDS consists of a 1.2m cube of lead with a tungsten target in the center where spallation neutrons are produced when bombarded with pulses of 800 MeV protons as discussed by the authors.

TL;DR: In this article, the possibility of applying this method to the measurement of the neutron-induced fission cross-section of short-lived actinides and in particular of the 77 eV isomer of 235 U is investigated.

TL;DR: A lead slowing-down spectrometer (LSDS) was recently installed at LANL as mentioned in this paper, which is comprised of a cube of pure lead 1.2m on the side, with a spallation pulsed neutron source in its center.
