Neon-20 nuclei have an elongated shape like a bowling-pin. Collisions of these nuclei create signals in how particles flow that clarify the role of nuclear geometry.

Using Nuclear Shapes to Study How Particles Flow in Collisions Between Light Ions

Collisions of oxygen and neon nuclei show how nuclear shapes can influence collective particle flow in small systems.

Physicists Propose a New Kind of Laser That Would Fire Neutrinos

A potential tool could use Bose Einstein condensates to produce intense beams of neutrinos.

KATRIN scientists test the system of magnets that control the fields inside the spectrometer.

KATRIN Narrows Down the Range of Neutrinos’ Mass

A direct search shows that neutrinos are at least a million times lighter than electrons.

A 3D view of the energy densities of electron neutrinos, electron anti-neutrinos, heavy-lepton neutrinos and heavy-lepton anti-neutrinos about five milliseconds after neutron stars collide.

When Neutron Stars Collide, Neutrinos Change Flavors

Scientists have developed a simulation of the merger of two neutron stars that includes the oscillation of different neutrino flavors into one another.
