| 21. | Upon irradiation, a thermal neutron interacts with the target nucleus via a non-elastic collision, causing neutron capture.
|
| 22. | Ancient and historic steel in Japan, India and Europe, a non-invasive comparative study using thermal neutron diffraction.
|
| 23. | A Helium-3 ( He-3 ) filled proportional counter is the most common epithermal and thermal neutron detector.
|
| 24. | Intermediate-energy neutrons have poorer fission / capture ratios than either fast or thermal neutrons for most fuels.
|
| 25. | This detector shows good efficiency at detecting fast neutrons in a background of thermal neutrons and gamma radiation.
|
| 26. | It will operate with thermal neutrons.
|
| 27. | Even comparatively low speed thermal neutrons cause neutron activation ( in fact, they cause it more efficiently ).
|
| 28. | The second most used fissile isotope plutonium-239 can also fission or not fission on absorbing a thermal neutron.
|
| 29. | The hexaboride has a low coefficient of thermal expansion and a high nuclear cross section for thermal neutrons.
|
| 30. | "This system uses a very simple technology, called thermal neutron analysis, " said Shea, the chief operating officer.
