This new isotope of oxygen, oxygen-28, was created when the team fired a beam of calcium-48 isotopes on a target of beryllium. Oxygen-16 has 8 neutrons and 8 protons, which provide it stability.

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 ...

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.

The oxygen isotope composition of phosphate (δ 18 O p) offers a powerful tracer for elucidating the complex pathways of phosphorus cycling in both terrestrial and aquatic ecosystems.

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.

A study of the upper atmosphere's composition has successfully measured an increased presence of the oxygen-18 isotope (18 O) compared to the lighter and most common isotope 16 O. Studies have shown ...

The researchers set up two experiments involving three stable isotopes of oxygen. These are oxygen-16 and oxygen-18, which both have zero nuclear spin, and oxygen-17, which has a nuclear spin of 5/2.

NEW DELHI: The Archaeological Survey of India (ASI) is conducting a study of the oxygen isotopes at an ancient fortified city in Vadnagar (Gujarat), where excav ...

Therefore, O-18 is an important substance indispensable for PET diagnosis but was difficult to procure because only 0.2% of naturally occurring oxygen is O-18.
