Double beta decay, one of the rarest nuclear processes, offers a unique portal into the fundamental properties of neutrinos and the conservation of lepton number. Experimental strategies have evolved ...

Physicists recently reported results of an experiment conducted in a salt mine one-half mile under Carlsbad, N.M., part of a decades-long search for evidence of the elusive neutrino-less double-beta ...

Neutrinos are ubiquitous, but mysterious. A Nobel prize was awarded this year for the discovery that they have mass, and undergo quantum oscillations as they travel - discoveries that fundamentally ...

Neutrino-free process: observing neutrinoless double beta decay could shed light on important mysteries of particle physics. A new technique to enable the detection of a hypothetical process called ...

In a new set of results, chemists have laid the foundation for a single-atom illumination strategy called barium tagging. Their achievement is the first known imaging of single atoms in a solid noble ...

Double beta decay research represents a pivotal field at the intersection of nuclear physics and particle physics, probing the fundamental nature of neutrinos and their role in the matter–antimatter ...

AMHERST, Mass. – Physicists Andrea Pocar and Krishna Kumar of the University of Massachusetts Amherst, part of an international research team, recently reported results of an experiment conducted at ...

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

April 24 (UPI) --The half-life of the isotope xenon-124 is a trillion times longer than the age of the universe. Observing such a slow decay would seem impossible, but scientists working on the XENON ...

Sheltered underneath nearly a mile of rock in Abruzzo, Italy, scientists are hard at work unraveling the secrets of the universe's smallest bits of matter. When a radioactive process called beta decay ...

Deep underground, in a cavern beside the Gran Sasso Tunnel in the Apennines Mountains near Rome, physicists are stacking blocks made of small, transparent crystals containing the isotope tellurium-130 ...
