Abstract: The radioactive nuclei neutron capture cross section is very important to nuclearsynthesis and nuclide abundance in sprocess， but it is difficult to be measured directly because of the target production. A new method， surrogate ratio method which is developed from surrogate method， could be used to determine the cross section of radioactive nuclei neutron capture. In this paper， the surrogate ratio method was introduced and the feasibility was discussed to deduce the desired neutron capture cross sections with surrogate ratio method.
