Neutron-production double-differential cross sections from heavy-ion interactions have been measured at Heavy-Ion Medical Accelerator in Chiba (HIMAC) of National Institute of Radiological Sciences (NIRS), Japan. 290-MeV/u O ions were bombarded upon a carbon target. The outgoing neutrons from the target were measured by a detection system that consist of two sizes of liquid organic scintillators with Time-of-Flight (TOF) technique in order to obtain a wide range of neutron spectrum from sub MeV to several hundred MeV. We have successfully measured the cross sections with a good precision.
