Double differential neutron yield (DDNY) for ¹²C⁶⁺ projectiles at116 MeV bombarded on thick ¹²C target is reported. Thick  target neutron yield data in energy range ∼ 10 MeV/nucleon is very sparsely available in literature. Time of flight technique was used to measure the kinetic energy distribution of the emerging neutrons. Angular distribution of emission was also studied using five small organic liquid scintillator detectors EJ 301, simultaneously, at five angles at a distance of 150 cm from the target and 30^◦ apart covering forward (0^◦) to backward (120^◦) angles. The experimental measurements were compared with statistical reaction code PACE2 and FLUKA outputs. The PACE2 and FLUKA calculations reproduce the measured thick target neutron spectra fairly well implying that compound nuclear emissions dominate the reaction process at these energies. The detailed energy distribution of emitted neutrons can be used for source term estimations in shielding calculation for the facility and it will also be useful in dose estimation due to secondary neutrons in the heavy or light ion therapy.
