Experimental values of high energy neutron flux in three energy ranges (11,5-20.8, 20,8-
32.7, 32,7-100 MeV (Fig.1) and spatial distributions of 88 Y, 87 Y, 86 Y and 85 Y isotope
production are presented for a QUINTA assembly. Deuteron beam energy range was from 1.0
to 6.0 GeV.
Monte Carlo simulation using MCNPX 2.6 code of the neutron flux density is roughly in
agreement with the obtained experimental data.
