Abstract
Angular distributions of fission fragments from the
neutron-induced fission of 232Th, 235U,
and 238U have been measured in the energy range 1-200 MeV
at the neutron time-of-flight (TOF) spectrometer
GNEIS using position sensitive multiwire proportional counters as fission fragment detector. A
short description of the experimental equipment and measurement procedure is given. The
anisotropy of fission fragments deduced from the data on measured angular distributions is
presented in comparison with experimental data of other authors.
