To initiate the fission of Uranium-230 (\(^{230}_{92}U\)), a low-energy neutron is typically required. This is because Uranium-230 is generally more susceptible to fission when it captures a neutron at a lower energy level, which allows it to become unstable and split into smaller nuclei. Higher-energy neutrons may result in the neutron passing by the nucleus without being captured. Therefore, the correct type of neutron for this process is a thermal neutron.
