The neutron capture reaction cross sections of ^151,153Eu are measured by the time-of-flight (TOF) method using the Kyoto University Research Reactor Institute-Linear Accelerator (KURRI-LINAC). For the prompt γ-ray measurement, a total energy absorption γ-ray detector of the BGO assembly was used for the neutron capture cross section measurement in the resolved resonance region. The present results of ¹⁵¹Eu are lager about 2 times than the JENDL-4.0 in the resonance of 3.36 eV.
