Jochen Stay, from the activist Anti-Atom Organization, called the transportation of nuclear waste by river "an act of irresponsibility beyond compare.
This new research, undertaken by the ALPHA experiment at CERN's Antiproton Decelerator (AD) in Geneva, is the first time that the electric charge of an anti-atom has been measured to high precision.
Earlier this year we made great strides towards this goal by inducing the first ever quantum transition in an anti-atom, a feat that holds great promise for measurements to come in the next five to 10 years.
So far, the only way we know whether we've caught an anti-atom is to turn off the magnet," says Fajans.
In an anti-atom, the antimatter equivalent of an ordinary atom, the electrical charges of all the component particles are reversed; while an ordinary atom has a positively charged nucleus with one or more negatively charged electrons orbiting it, the antimatter atom has a negatively charged nucleus with positively charged orbiting electrons.
Now, 60 or 70 years down the road, we have just witnessed the first-ever microwave interactions with an anti-atom.
Scientists there are using a machine which can produce an anti-atom which is in turn used by scientists to probe the differences between matter and anti-matter to find out if these elements played a part in the start of the universe.
In a study of quantum phenomena and physical problems, Nesvizhevsky and Voronin discuss the wave nature of microscopic objects like neutrons, atoms, and anti-atoms, which they manifest while bouncing on surfaces in a gravitational field.
Only the most lethargic anti-atoms were caught in the magnetic traps.
The idea of anti-atoms and antimolecules has captured the public's imagination.
That trap was only "deep" enough to capture the slowest-moving anti-atoms.
