MEASUREMENT OF THE MAIN CHARACTERISTICS OF PuBe AND 238PuBe NEUTRON SOURCES USING BONNER SPHERE SPECTROMETER WITH A 3He-COUNTER

East European Journal of Physics, 2017
The energy and pulse height spectrum of PuBe and 238PuBe neutron sources are measured without taking into account scattered radiation, taking into account this radiation (without the shadow cone) and own scattered radiation from these sources (with a ...
