The main objective of this proposal is the study of rare flavour changing neutral current transitions in b-hadrons, where a b-quark decays
to an s- or d-quark and a pair of muons.
But other figures show that in some areas of Cardiff and the Valleys the picture is even worse, with a shocking 84 per cent of five-year-olds in Rhondda Fach showing evidence of tooth decay
are detected in real time using the scintillation light produced in the helium by the beta-decay
A beryllium-7 nucleus decays
into a lithium-7 atom by absorbing an electron, which converts a proton into a neutron.
A radioactive element is an element with an unstable nucleus that decays
Fungi associated with principal decays

The collaborators came up with values for nine quantities, most of which are related to particle decays
and energy states of a variety of mesons and baryons.

In the studies of such decays
at Brookhaven since the late 1980s, physicists there created kaon beams and observed the particles' fates using house-size detectors.
An electrostatic cylinder with a potential of 25 kV defines the detected region of neutron decays
For decades, textbooks have listed bismuth-209 as the heaviest naturally occurring atom that never decays
Because free neutron decay
is unencumbered by the many-nucleon effects present in all other nuclear decays
, measurements of the parameters that describe neutron decay
can be related to the fundamental weak couplings in a straightforward fashion.
When a neutron decays
in an unstable nucleus, the particle transforms into a proton, while an electron and an antineutrino flee the scene.
