| 1. | Nihonium is a highly unstable element and decays by emitting alpha particles.
|
| 2. | It decays by emitting alpha particles and gamma radiation to become neptunium-237.
|
| 3. | Each time an alpha particle reached the screen it produced a flash.
|
| 4. | Neutron absorption produces a tritium ion, an alpha particle, and kinetic energy.
|
| 5. | The nuclear microprobe's beam is usually composed of protons and alpha particles.
|
| 6. | By identifying characteristics of emitted alpha particles they found the new elements.
|
| 7. | The alpha particle is trapped in a potential well by the nucleus.
|
| 8. | Lunar soil surveys were completed using photographic and alpha particle backscattering methods.
|
| 9. | Package radioactive decay usually causes a soft error by alpha particle emission.
|
| 10. | Lithium is also used as a source for alpha particles, or helium nuclei.
