Abstract

In Russian Technical Physics Institute (Snezhinsk) neutron and gamma-ray yields were measured for Al, Ti, Fe, Pb, U-238. The experimental cross sections were analyzed. Experimental and calculated data were compared. The calculations were made by MCNP code (USA) with ENDF/B-5 nuclear data. Considerable discrepancy was discovered. Therefore nuclear data these elements are is need of correction.
