Two ionization fission chambers
placed in fast neutron beam # 5 (see figure in "Main
page"). First one containes foils of actinide material and are used
in work "Neutron
induced fission cross-sections of 233U,
238U,
232Th,
237Np
and 239Pu
relative to 235U
from 1 MeV to 200 MeV". Second one containes foils
of natPb
and Bi and are used in work "Neutron
induced fission cross-sections of lead and bismuth relative to 235U
in the energy range 30 - 200 MeV". |
