muon造句
1. Like the electron, the muon acts like a tiny bar magnet. 2. It has come from experiments with high-energy muon neutrino beams at particle accelerators, and from lower-energy neutrinos at two nuclear reactors. 3. The first theoretical calculations on various characteristics of muon catalysed fusion appeared during the 1950s, by Yu. 4. Guido Tonelli, spokesman for the Compact Muon Solenoid detector group, insisted that it would be a major scientific development whether the existence of the missing particle is included or excluded. 5. The reconstruction method of muon tracks in the L 3 Cosmic Ray Experiment has been studied. 6. The Muon Counter is one of the important detectors in BES. 7. However, in muonic hydrogen the Lamb shift is much more dependent on the proton radius because the much heavier muon spends more time very near to – and often within – the proton itself. 8. Scientists from the LHC's Compact Muon Solenoid detector has now totted up all of the resulting particle interactions. 9. A prototype of the readout electronics for BES Muon Counter is introduced. 10. Whenever a muon collides with a hydrogen molecule, it knocks the molecule apart and replaces the electron to create muonic hydrogen. 11. About 1% of the time the muon finds itself in the 2S state, where it can be excited to the 2P state by absorbing a photon from a laser pulse. The 2P state then decays with the emission of an X-ray. 12. However, nobody had made the conclusive step of considering the consequences of this, namely the chain of muon catalysis reactions. 13. The virtual particle can interact with the magnetic field and affect the moment of the muon. 14. Going this deep would help reduce the background signals from cosmic ray muon particles. 15. Then there are neutrinos, W and Z bosons, the electron-like muon and tau particles, and gluons—which hold quarks together in groups. 16. The team prepares a beam of just one type, muon neutrinos, sending them from Cern to an underground laboratory at Gran Sasso in Italy to see how many show up as a different type, tau neutrinos. 17. Neutrinos are known to switch back and forth between their three observed types (electron, muon and tau neutrinos), and OPERA was originally designed to detect these shifts. 18. Another strange thing about neutrinos is that they come in at least three types or "flavours" – tau[/muon.html], electron and muon – and can morph from one flavour to another. 19. When a neutrino collides with an atomic nucleus, a new particle called a muon is produced, which emits a faint blue glow in the transparent ice that the DOMs can detect. 20. The surprising result was obtained by studying "muonic" hydrogen in which the electron is replaced by a much heavier muon. 21. Several experimental results on solar neutrino missing and on atmospheric muon neutrino missing are described. 22. But they could also be easily mistaken for the far more common muon.
