Nuclear physicists on the hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights ...

Nuclear physicist's voyage toward a mythical island

Theories were introduced as far back as the 1960s about the possible existence of superheavy elements. Their most long-lived nuclei could give rise to a so-called "island of stability" far beyond the element uranium. However, ...

Experiment to precisely measure electrons moves forward

A new probe of the humble electron may provide insight into the forces at work inside the heart of matter. Now, the MOLLER experiment at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility is one ...

Characterising cold fusion in 2-D models

Progress towards 'cold fusion,' where nuclear fusion can occur at close to room temperatures, has now been at a standstill for decades. However, an increasing number of studies are now proposing that the reaction could be ...

Understanding ghost particle interactions

Scientists often refer to the neutrino as the "ghost particle." Neutrinos were one of the most abundant particles at the origin of the universe and remain so today. Fusion reactions in the sun produce vast armies of them, ...

The mystery of the neutron lifetime

Nine seconds. An eternity in some scientific experiments; an unimaginably small amount in the grand scheme of the universe. And just long enough to confound nuclear physicists studying the lifetime of the neutron.

Looking skin deep at the growth of neutron stars

In atomic nuclei, protons and neutrons share energy and momentum in tight quarters. But exactly how they share the energy that keeps them bound within the nucleus—and even where they are within the nucleus—remain key ...
