Experimental Measurement of Infinite Dilution Thermal Neutron Self-shielding Factor

Abstract The absorption of neutrons in media together with its transport properties cause the neutron flux to decrease as it penetrates material because sample itself attenuates goes deeper into sample. In present work, thermal self-shielding factors indium, gold, zinc, and mercury were determined experimentally. current results those found literature used validate a mathematical ab initio formulae based on integral cross-section parameters compare our results. complete agreement among these species data suggests validity correlating migration length convex-shaped average chord described model.
