Lithium has at least three possible sources of origin: formed via collisions of heavier cosmic-ray nuclei, created during the Big Bang, and produced from the decay of beryllium (7 Be) in low-mass ...

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 ...

"The horizontal direction on the muon is very relevant," said de Jong. Muons can also be formed in cosmic-ray spallation, wherein a cosmic ray enters Earth's atmosphere and collides with a ...

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 ...

“The radionuclide beryllium-10 is continuously produced in the upper atmosphere by cosmic ray spallation mainly on nitrogen and oxygen.” “The residence time of beryllium-10 in the atmosphere is on the ...

ORNL and Argonne researchers have used neutron scattering at the Spallation Neutron Source and X-Ray scattering at the Advanced Photon ... that will shield neutrinos passing through from cosmic rays. ...

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.

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 ...
