Multi-section fission ionization chamber for measurement of 239Pu(n,γ) reaction in fission tagging method
/ Perkowski, J (Lodz U.) ; Alcayne, V (Madrid, CIEMAT) ; Andrzejewski, J (Lodz U.) ; Cano-Ott, D (Madrid, CIEMAT) ; Gawlik-Ramięga, A (Lodz U.) ; Mendoza, E (Madrid, CIEMAT) ; Sánchez-Caballero, A (Madrid, CIEMAT) ; Sibbens, G (Geel, JRC) ; Vanleeuw, D (Geel, JRC) ; Aberle, O (CERN) et al.
The 239Pu(n,γ) reaction cross section is very important for operation of both thermal and fast reactors, when loaded with MOX fuels. According to the NEA/OECD High Priority Request List the precision of cross section data for this reaction should be improved. [...]

A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
/ Bacak, M (CERN ; TU Vienna ; IRFU, Saclay) ; Aïche, M (CENBG, Gradignan) ; Bélier, G (CEA DAM) ; Berthoumieux, E (IRFU, Saclay) ; Diakaki, M (IRFU, Saclay) ; Dupont, E (IRFU, Saclay) ; Gunsing, F (IRFU, Saclay ; CERN) ; Heyse, J (Euratom, Geel) ; Kopecky, S (Euratom, Geel) ; Laurent, B (CEA DAM) et al.
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called $fission-tagging$ or $fission-veto technique$. For this purpose a new compact and fast fission chamber has been developed. [...]

Neutron-induced fission reactions play a crucial role in a variety of fields of fundamental and applied nuclear science. In basic nuclear physics they provide important information on properties of nuclear matter, while in nuclear technology they are at the basis of present and future reactor designs. [...]

High-precision prompt- γ -ray spectral data from the reaction Pu241 ( nth , f )
/ Oberstedt, S ; Billnert, R ; Belgya, T ; Bryś, T ; Geerts, W ; Guerrero, C (CERN) ; Hambsch, F -J ; Kis, Z ; Moens, A ; Oberstedt, A et al.
In this paper we present results from the first high-precision prompt-γ-ray spectral measurements from the reaction Pu241(nth, f). Apart from one recent experiment, no data are reported in the literature for this fissioning system, which motivated a new dedicated experiment. [...]
