Abstract：
The neutron yields and the neutron emission rates in the forward direction for 50MeV/u ¹⁸O-ion induced reactions on thick Be, Cu, Au targets have been measured using the threshold detector activation method. The measured results indicate that the neutron yield and the neutron emission rate depend on the atomic number of target nuclei; neutron yield for the lighter target is greater than that for the heavier one. The neutron yield for 50MeV/u ¹⁸O-ion on Cu is about four times as large as that for 50MeV/u ¹²C-ion on Cu when incident energies per nucleon are identical.
