Vd. Sevastyanov et al., MEASUREMENT OF SPECTRUM OF NEUTRONS GENERATED BY 70-MEV PROTONS IN A THICK ALUMINUM TARGET, Instruments and experimental techniques, 38(3), 1995, pp. 304-307
This paper describes the technique and results for measuring the spect
rum of neutrons generated in a ''thick'' aluminum target by protons of
a beam from the U-240 isochronic cyclotron at the Institute for Nucle
ar Research of the Academy of Sciences of Ukraine. The proton energy i
s similar to 70 MeV. The spectrum has been measured in an energy range
of 0.5 eV-55 MeV using neutron activation and time-of-flight techniqu
es.
