How To Use Beta decay In A Sentence
-
The aim is to use the detector to try to observe a theoretical atomic event called neutrinoless double-beta decay - a radioactive process whereby an atomic nucleus releases two electrons and no neutrinos.

-
Most beta decays involve the emission of electrons from the nucleus as a neutron decays into an electron and a proton.
-
They will be looking for a characteristic spectrum to emerge from the detectors when a neutrinoless double beta decay is detected - "like a rounded curve with a bump at the end on top of background noise" is how Kouzes put it.

CUORE scientists will wait for neutrinoless double-beta decay to happen in a 750-kilogram cube of tellurium dioxide placed under 1,400 metres of rock at the Gran Sasso laboratory.

I moved to the larger machine where I continued to do some weak interaction experiments, like for instance the determination of the parity violation in the beta decay of the lambda hyperon.

-
The emission of the electron's antiparticle, the positron, is also called beta decay.
-
The committee recommends that the properties of neutrinos be determined through a well-coordinated, staged program of experiments developed with international planning and cooperation. • A phased program of searches for the nature of neutrino mass (using neutrinoless double beta decay) should be pursued with high priority. • DOE and NSF should invite international partners to initiate a multiparty study to explore the feasibility of joint rather than parallel efforts in accelerator-based neutrino experiments.
The Future, By Committee
-
At that time Kai Siegbahn had for a number of years developed more and more sophisticated instruments for analyzing electrons emitted at the decay of certain radioactive nuclei - so called beta decays.

-
This is the force responsible for nuclear beta decay, which, for example, permits a neutron to decay into a proton, electron, and a third particle -- the neutrino which without extremely carefully designed experiments leaves no observable signatures of its own strictly speaking, it is the neutrino's antiparticle known as the antineutrino.
Lisa Randall: CERN or Einstein? Interpreting the Findings
-
This new weak current had also to be electrically charged because in beta decay the neutral neutron turns into a positive proton.
-
As beta decay does not change the atomic mass, the isotope of the new element number 93, neptunium, also has mass 239.
-
Some atoms can undergo radioactive beta decay, in which a neutron decays into a proton, an electron and an electron-antineutrino via the weak nuclear force.
-
In FY 2010 DOE's Office of Nuclear Physicsallocated $20 million over the next four years to the Majorana Demonstrator Project, which is aimed at capturing neutrinoless double beta decay events.

With the help of a 60-kilogram array of ultrapure germanium-76 detectors housed deep underground where external background sources are at a minimum, the collaborators hope to observe the handful of neutrinoless double beta decay events taking place each year.
