Abstract: Unshielded value of the total neutron cross section of the natHf at the neutron 2 keV energy was obtained. The MCNP 4 code and measurement results obtained with using six samples for thicknesses from 0.00236 to 0.01257 nucl/b were used for determination of the unshielded value of the natHf cross section. Obtained value of the total neutron cross section of the natHf was compared with the data of other authors and with data from the evaluated nuclear data libraries.

Keywords: total neutron cross section, natHf, resonance self-shielding factors, MCNP 4 code.
