The thermal activation cross section of H-3 is a measure of the probability that a hydrogen-3 atom will undergo a nuclear reaction when it is bombarded by thermal neutrons.
The thermal activation cross section of H-3 is determined through experiments where the number of reactions that occur between thermal neutrons and H-3 atoms is measured and compared to the number of neutrons that were present.
The thermal activation cross section of H-3 is important in nuclear physics and reactor design, as it helps us understand how H-3 atoms interact with thermal neutrons and how they can potentially be used as a fuel source.
The thermal activation cross section of H-3 is relatively low compared to other isotopes, such as uranium and plutonium. This means that H-3 is not as efficient as a fuel source for nuclear reactions.
Yes, the thermal activation cross section of H-3 can be altered by changing the energy of the neutrons, the temperature of the environment, or the presence of other particles that may affect the interaction between the neutron and H-3 atom.
