A nano-diamond is an attractive neutron reflection material below cold neutron energy. The total neutron cross section of a nano-diamond was derived from a neutron transmission measurement over the neutron energy range of 0.2 meV to 100 meV because total neutron cross section data were not available. The total cross section of a nano-diamond with particle size of approximately 5 nm increased with a decrease in neutron energy to 0.2 meV. It was approximately two orders of magnitude larger than that of graphite at 0.2 meV. The contribution of inelastic scattering to the total cross section was to be shown negligible small at neutron energies of 1.2, 1.5, 1.9, 2.6, and 5.9 meV in the inelastic neutron scattering measurement. Moreover, small-angle neutron scattering measurements of the nano-diamond showed a large scattering cross section in the forward direction for low neutron energies.

Total neutron cross sections for La and Pr in the energy range from 20 to 240 keV were measured by using monochromatic neutrons, which were produced by the Li(p,n)Be reaction. Theenergy spreads of incident neu- trons were about 18 keV for La and about 8 keV for Pr. The measured total neutron cross sections, with statistical error of 2 - 5% for La and 2 - 3% for Pr, were compared with other available data. The average total neutron cross-section data for both nuclides were interpreted in terms of a spherical optical-model potential. S-wave strength functions S for La and Pr were deduced from the optical-model parameters obtained by fitting to the average total neutron cross-section data; i.e. S = 0.46 10 for La and S = 1.0 10 for Pr. The result of total neutron cross sections for La in the energy range from 70 to 140 keV with the energy spreads of about 2.8 keV is also presented.
