Modern re-run shows that Arthur Ruhlig’s conclusions, which probably influenced early thinking about fusion energy, were ...

Deuterium (heavy hydrogen), for instance, has one proton and one neutron in its nucleus. When two deuterium nuclei are fused together, they form a helium nucleus (two protons and two neutrons ...

Cold fusion, better known by its practitioners as LENR, is the science—or, perhaps, the art—of making atomic nuclei merge and, ideally, harnessing the resultant energy.

Deuterium, an isotope of hydrogen, is abundant in water, making it a reliable source for fusion reactions. By fusing ...

Inside the reactor, deuterium and tritium nuclei collide and fuse, releasing helium and neutrons. (Image: IAEA/M. Barbarino) Reaching for the stars . While the sun’s massive gravitational force ...

In the case of zero-field nuclear magnetic resonance (zero-field NMR), there is no need for a powerful external magnetic field. Here, the intramolecular couplings between the spins of magnetically ...

Two Los Alamos Laboratory scientists discovered Arthur Ruhlig’s major contributions to fusion physics, and they did so completely by accident.

Noting that deuterium nuclei are heavier than hydrogen, the researchers reasoned that they should be less delocalized than protons and thus should require more pressure to transition.

Because these deuterium nuclei are roughly double the weight of a speeding neutron, heavy water is way less good at slowing neutrons down than regular old light water is.

If the particles are made hot enough, the deuterium nuclei will collide with ample force to “fuse” together, forming helium 3 and giving off a neutron. When that happens, ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...
