Radioactivity is the act of emitting radiation spontaneously and is done by an atomic nucleus (unstable) to attain a more stable configuration by giving up some energy. Radioactivity is a physical, ...

Physicists got their first look at the structure of the atomic nucleus. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The Geiger-Marsden ...

To understand nuclear decay equations. How to measure the activity of radioactive sources. Spontaneously means that the process of radioactive decay can not be speeded up or slowed down by physical ...

Alpha particle radioluminescence detection and imaging is an advanced optical technique that capitalises on the light emitted when alpha particles interact with air molecules. When alpha particles – ...

Theoretical calculations predict a complex excited state (0+) for helium-4 (4He) at the 20.21 MeV energy level. This state involves a coupling of three cluster configurations: hydrogen-3 and a proton, ...

However, as the number of protons increases, more neutrons are needed to keep the nucleus stable. For example lead (lead-206) has 82 protons and has 124 neutrons. If the nucleus has too few neutrons, ...

This is an example track of an alpha particle (energy 15 MeV) from the test beam registered with the demonstrator detector mini-eTPC. Read-out electrodes of the detector are parallel to the X-Y plane, ...

A promising approach to treating cancer - called targeted alpha-particle therapy or TAT - could better harness the curative power of radiation treatments and lessen the severity of their more ...
