| 41. | The 6 Li has a high cross-section for thermal neutron absorption through the 6 Li ( n, ? ) reaction.
|
| 42. | The 10 B isotope is useful for capturing thermal neutrons ( see neutron cross section # Typical cross sections ).
|
| 43. | The excitation energy within the compound nucleus is formed from the binding energy of the thermal neutron with the target nucleus.
|
| 44. | Natural uranium is 99.284 % nuclide existing in nature ( in any appreciable amount ) that is fissile with thermal neutrons.
|
| 45. | A " thermal neutron " is a free neutron that is kinetic theory " for energies and speeds of molecules ).
|
| 46. | And better mine detectors _ using radar, microwaves, lasers or thermal neutron analysis _ won't be available for five to 10 years.
|
| 47. | While a nuclear bomb working on thermal neutrons may be impractical, modern weapons designs may still benefit from some level of moderation.
|
| 48. | Its precursor 235 U and thermal neutrons ) but also has the highest known thermal neutron capture cross section of any nuclide.
|
| 49. | Its precursor 235 U and thermal neutrons ) but also has the highest known thermal neutron capture cross section of any nuclide.
|
| 50. | Beside thermal neutrons, a cold moderator of liquid deuterium ( cold source ) slows neutrons down and shifts their spectrum to lower energies.
