Neutron-production double-differential cross sections for 290 MeV/u carbon-ion incidence on car- bon target were measured with NE213 liquid organic scintillators by time-of-flight technique. NE213 liquid organic scintillators 12.7 cm in diameter and 12.7 cm thick were placed in the directions of 15°, 30°, 45°, 60°, 75° and 90°. The typical flight path length was 4.0 m. In order to reduce neutrons from the beam dump, an iron and a concrete shield was placed between the detectors and the beam dump. For measurement of background, a shadow bar was set between the target and each detector. Neutron detection efficiencies were obtained by calculations with a Monte Carlo sim- ulation code SCINFUL-QMD. The cross sections were obtained for neutron energy above 2.8 MeV. The experimental results were compared with the calculation data of the PHITS code.
