In nuclear beta decay an up quark ‘u’ in a proton converts into an up down quark ‘d,’ turning the proton into a neutron and emitting a positron and a neutrino. This work affects ...

Beta decay causes the atomic number of the nucleus to increase by one while the mass number remains the same. Gamma ray emission causes no change in the number of particles in the nucleus ...

They succeeded in the measurement of the bound-state beta decay of fully-ionized thallium (²⁰⁵Tl⁸¹⁺) ions at the Experimental Storage Ring (ESR) of GSI/FAIR. This measurement has ...

New experiments on thallium decay have helped determine the Sun formed over 10–20 million years, improving stellar nucleosynthesis models. Have you ever wondered how long it took our Sun to form in ...

Here is the equation for the alpha decay of radon-219 into polonium. Beta decay involves the conversion of a down quark to an up quark. This changes a neutron into a proton plus an electron.

The AMoRE experimental collaboration in South Korea has reported not finding evidence of neutrinoless double beta decay after a two-year search, imposing stringent limits on this mysterious, ...

The effects of the weak force were first discovered at the turn of the 20th century, in the place where it is most obviously at work: in radioactive beta decay. In the most common form of this ...
