Description
Four Timepix3 pixel detectors were installed
on the body of Actar TPC demonstrator during
the November 2021 beamtime of the IS581 experiment.
Polyethylene converters were used for detection
of fast neutrons. Since no significant background
was observed, it was possible to measure the angular
distribution of emitted neutrons. Subsequent simulations
emplying the results of Talys code and available data
on fragment distributions allowed to estimate directly the value
of fission barrier height for neutron-deficient nucleus
210Fr, which was a main goal of the IS581 beamtime.
