Short description: For protons, the Monte Carlo simulations consisted of a cylindrical target irradiated with a uniformly distributed, zero divergence, monoenergetic (113
MeV or 256
MeV) proton beam of radius equal to the radius of the target. For carbon ions, a monoenergetic carbon ion beam of 0.25 cm radius, 290
MeV/u energy and zero divergence was simulated. The target was a water phantom of 18 cm thickness.

Reference data: Experimental neutron yields from thick targets of different materials bombarded by protons of energies below 256
MeV were obtained from references [1][2]; for carbon ions interacting in water the data was obtained from reference [3].
