Neutron yields and emission rates of 50 MeV/u 18O-ion on thick Be, Cu and Au targets

The neutron yield and the neutron emission rate are very important parameters in neutron dosimetry and shielding studies of heavy ion reactions. Total neutron yields and neutron emission rates in the forward direction for 50 MeV/u 18O-ion on thick Be, Cu and Au targets have been measured using an activation technique. The results indicate that neutron yields and emission rates in the forward direction depend on the atomic number of target nuclei, i.e. the lighter target has greater neutron yield and neutron emission rate. The neutron yield of 18O-ions is greater than that of 12C-ions when target nucleus and incident energy per nucleon are identical. (orig.)
