The origin of lithium (Li), the third element of the periodic table, has long been shrouded in mystery. This element, commonly found in cosmic rays as two stable isotopes, 6Li and 7Li, is crucial ...

Beryllium-7 is a cosmogenic radionuclide produced in the upper atmosphere by cosmic ray spallation of nitrogen and oxygen. The nuclear reaction produces BeO or Be(OH) 2 which diffuse through the ...

Muons can also be formed in cosmic-ray spallation, wherein a cosmic ray enters Earth's atmosphere and collides with a molecule or atom, smashing it apart into a shower of subatomic particles.

Beryllium-10 is a rare radioactive isotope and is formed in the Earth's atmosphere mainly by cosmic ray spallation of nitrogen and oxygen. It provides valuable insights into the Earth's geological ...

Koll et al. report on the discovery of an anomaly in the beryllium-10 concentration profiles of several deep-ocean ferromanganese crusts (stars) from the Central and Northern Pacific during the Late ...

ORNL and Argonne researchers have used neutron scattering at the Spallation Neutron Source and X-Ray scattering at the Advanced Photon Source to examine samples of amorphous materials – substances ...

The most powerful cosmic-ray electrons and positrons ever detected slamming into Earth's atmosphere carry energies so high they can only have come from relatively close by, new research has revealed.

High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S.. Physical Review Letters , 2024; 133 (22) DOI: 10.1103/PhysRevLett.133.221001 Cite This Page : ...

These energy losses are especially significant for the most energetic electrons and positrons, known as cosmic-ray electrons (CRe), whose energy exceeds one teraelectronvolt (TeV) (i.e. 1000 ...
