The neutron total cross section of 10B has been determined between 90 and 420 keV neutron energy by means of a transmission measurement on a boron sample enriched in 10B. Deviations in shape from other measurements are within the statistical accuracy of the present measurement and are smaller than 1.5%. In the measured energy region, no indication of narrow resonance structure was found, and the deviation of the total cross section from an E−1/2 energy dependence above 100 keV was confirmed. An analysis using the R-matrix formalism showed that this deviation can be associated with the 7/2+ s-wave resonance at 370 keV.
