Neutrons produced by 75 MeV/u 12C-ion on thick targets

摘要

Fluence rates and angular distributions of the neutron emitted by75 MeV/u 12C-ion bombardment on thick Be and An targets have been measured bymeans of the threshold detector activation method. Based on that, the neutron yields,emission rates in the forward direction and neutron dose equivalent rate distributionswere deduced.
