| 1. | The neutron cross section is defined for a given type of target particle.
|
| 2. | As the neutron energy increases, the neutron cross section of most isotopes decreases.
|
| 3. | The cyclotron would be used for measurements of the neutron cross section of plutonium.
|
| 4. | It is also dependent on the nuclei it strikes and its neutron cross section.
|
| 5. | And he designed the reactor oscillator, a machine used to measure neutron cross sections.
|
| 6. | The larger neutron cross section, the more likely a neutron will react with the nucleus.
|
| 7. | Enrico Fermi's purported comment when he observed the neutron cross section for boron, " My God!
|
| 8. | The lanthanides have large neutron cross sections and hence they would poison a neutron driven nuclear reaction.
|
| 9. | Another, "'Sombrero "', uses a reaction chamber built of Carbon-fiber-reinforced polymer which has a very low neutron cross section.
|
| 10. | The 10 B isotope is useful for capturing thermal neutrons ( see neutron cross section # Typical cross sections ).
