The neutron capture cross sections for ¹⁵⁹Tb and ¹⁶⁹Tm relative to the ¹⁹⁷ Au (n, γ) ¹⁹⁸ Au reaction are measured at neutron energies of 0.57, 1.10 and 1.60 MeV by using the activation method. The activities of the products are measured with a high resolution HPGe detector gamma-ray spectrometer. The errors of the present work are 5~6% for Tb, 6~7% for Tm. The recommended data in energy region of 0.4~3.0MeV are given as compared with other data published previously.
