MR. D. L. CHAPMAN'S argument appears essentially to be similar to that already developed from a quite different point of view by Lindemann (Phil. Mag., 1919, vol ...

Researchers have discovered eight new rare isotopes of the elements phosphorus, sulfur, chlorine, argon, potassium, scandium and, most importantly, calcium. These are the heaviest isotopes of these ...

Analysis of Apollo-return samples revealed that the chlorine content and isotope compositions of lunar samples are unique compared with Earthly and other materials, such as meteorites, suggesting that ...

Sulfur and chlorine isotopes in the atmosphere of Jupiter’s moon Io indicate that it has been volcanically active for the entire 4.57 billion-year history of the Solar System, according to a new study ...

Lunar mare basalts are depleted in F and Cl by approximately an order of magnitude relative to mid-ocean ridge basalts and contain two Cl-bearing components with elevated isotopic compositions ...

The inside of the moon isn't as watery as previously reported, according to a new study that found a high variety of chlorine atoms in Apollo moon rocks. For decades scientists had thought the moon is ...

Ultrafine measurements of atmospheric gases could help track down persistent sources of CFCs thought to be slowing the recovery of the ozone layer. The use of the refrigerants and aerosol propellants ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

THE method outlined in our letter of September 30, 1920 (NATURE, vol. cvi., p. 144), and used for the partial separation of the isotopes of mercury, has enabled us to accomplish a partial separation ...
