Sentences with phrase «in ordinary hydrogen»

Now, Jeffrey Hangst, an experimental physicist at Aarhus University in Denmark, and his 48 colleagues at the ALPHA collaboration at CERN have precisely measured the energy difference between antihydrogen's lowest energy state, called the 1S, and a higher energy state known as the 2S, by far the most precisely measured transition in ordinary hydrogen.

Not exact matches

At present, the density of ordinary baryons and radiation in the universe is estimated to be equivalent to about one hydrogen atom per cubic metre of space.

The Big Bang theory makes detailed predictions about the total number of ordinary atoms and about the relative abundance of deuterium (heavy hydrogen) and helium in the universe.

Next, Agee and his colleagues used a laser to extract water molecules trapped within minerals in the meteorite and fed them into a mass spectrometer to calculate the ratio of deuterium, a heavy isotope of hydrogen, to ordinary hydrogen.

Hydrogen is the main element of ordinary matter (5 %) in the Universe, which is primarily composed of more abundant dark matter (27 %) and dominant dark energy (68 %).

Ordinary «bulk» silicon with high concentrations of hydrogen implanted in the crystal lattice showed some promise, but to «dope» silicon in this way meant bombarding it with ion beams, which damages it.

The ordinary hydrogen - burning dwarf stars like the Sun are found in a band running from top - left to bottom - right called the Main Sequence.

Although many scientists believe that Venus may once have had oceans of water on its surface (in part because its ratio of deuterium to ordinary hydrogen is now measured to be around 150 times that of the Earth's), most of it has been lost the past five billion years.

Heavy water: Water containing a significantly greater proportion of heavy hydrogen (deuterium) atoms to ordinary hydrogen atoms than is found in ordinary (light) water.

That Venus had a primordial ocean, with most of the water subsequently lost to space, is confirmed by the present enrichment of deuterium over ordinary hydrogen by a factor of 100 [107], the heavier deuterium being less efficient in escaping gravity to space.
