NMR makes use of specific stable isotopes, commonly 13 C, but there is only one NMR-active stable isotope for oxygen, 17 O. The effects of using this oxygen isotope over other isotopes include ...

For billions of years, Earth has been bombarded by tiny particles of rock and metal from space. When these extraterrestrial ...

The most abundant form of oxygen, 16 O, is doubly magic, because of its eight protons and eight neutrons. Oxygen-28, with 8 protons and 20 neutrons, has long been predicted to be doubly magic, too.

Scientists discovered hints of the new isotope, called nitrogen-9, by smashing beams of oxygen isotopes into beryllium atoms in the U.S. National Superconducting Cyclotron Laboratory.

Concentrations of the oxygen-18 isotope (δ18O) in precipitation are dependent on temperature and distance traveled from the moisture source. Snow during the pre-monsoon season of 2012, arriving from ...

The paper, titled Distinct oxygen isotope compositions of the Earth and Moon, may challenge the current understanding of the formation of the Moon.

Isotopes are versions of an atom, in this case, oxygen, which has a different mass than usual due to having a different number of neutrons. If an isotope is heavier, it is more likely to stay in a ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying ...
