During electron-impact ionization (EII), high-energy electrons collide with atoms, knocking away one or more of their outer electrons. To calculate the probability that ionization will occur during these impacts, researchers ...
There is a lot going on inside atomic nuclei. Protons and neutrons are whizzing around and interacting with each other. The movement of the nuclear particles and their intrinsic angular momentum induce magnetic moments. Together, ...
Nuclear fusion—when two nuclei combine to form a new nucleus, thereby releasing energy—may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production.
Colliding heavy atomic nuclei together creates a fluidlike soup of visible matter's fundamental building blocks, quarks and gluons. This soup has very low viscosity—a measure of its "stickiness," or resistance to flow.
Few things last very long in the world of the open oceans, it would seem. In the light-filled surface layer, microscopic algae convert carbon dioxide and water into biomass via photosynthesis. Individual cells vanish in a ...
The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study.
Tokamaks are one of the most widely studied technologies in the global effort to achieve sustained nuclear fusion. Using intense magnetic fields, they confine superheated plasma within their doughnut-shaped interiors, allowing ...
The role of atomic weapons has become more prominent and nuclear states are modernizing arsenals as geopolitical relations deteriorate, researchers said Monday, urging world leaders to "step back and reflect".
An experiment by a group of physicists led by University of Rochester physics professor Regina Demina has produced a significant result related to quantum entanglement—an effect that Albert Einstein called "spooky action ...
An international team of scientists has developed a novel way to experimentally produce plasma 'fireballs' on Earth.
