Certain isotopes such as Indium-115 (In-115) are extremely long lived, taking over 100 trillon years for half of the Indium atoms to decay away. These isotopes allow scientists to probe the precise ...

Results from KATRIN and MicroBooNE strongly disfavour a light sterile-neutrino explanation of longstanding anomalies.

Neutrino mass measurements remain one of the most challenging endeavours in contemporary physics. Direct measurement techniques, particularly those probing the endpoint of the tritium β-decay spectrum ...

A free neutron outside a nucleus is not stable. It undergoes beta decay at a probability. Over time, the number of free neutrons decreases exponentially at a time constant, which is called the neutron ...

In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as neutrinoless double beta (0νββ) decay. This is a rare process that entails ...
