The cross sections of the 10B(n,)7Li two-body and 10B(n, t2
) three-body reactions have been measured at
, 4.5 and 5.0 MeV using a GIC (twin gridded ionization chamber) and an enriched thin-film 10B sample in 2017. The anode and grid signals of the GIC are used in the experiment. However, we found afterwards that better results can be obtained using the anode and cathode signals of the GIC. In the present work, Monte Carlo simulations of the measurement are performed. Then, the cathode signals are rebuilt using the anode and grid signals of the GIC. Finally, the experiment data are re-analyzed to obtain new results with smaller uncertainties especially for the 10B(n, t2
) three-body reaction. The present results are compared with existing measurements and evaluations.
