Sentences with phrase «heavy as a proton»

Not exact matches

Cosmic rays zooming through space sometimes crash into heavier atoms, knocking off protons and neutrons and creating elements such as beryllium and lithium.
More important, a convergence of observations suggests that cosmic neutrinos spring from the same astrophysical sources as other particles from space: highly energetic photons called gamma rays, and mysterious ultra-high energy cosmic rays — protons and heavier atomic nuclei that reach energies a million times higher than humans have achieved with particle accelerators.
For example, TA physicists argue that — as most physicists expected — the highest energy rays are protons, whereas Auger physicists argue they may include heavier atomic nuclei.
To make the reactor run, extra neutrons must be supplied from another source, such as a proton beam hitting a heavy metal target.
Up to now, platinum has been the most efficient spin - charge converter material, as it is a heavy metal, and the spin - orbit coupling of heavy metals is known to be especially strong due to the large amount of protons (positive charge) in their core.
A captured neutron can either stay as it is, simply making a heavier isotope of the element it crashed into, or it can decay into a proton, creating a whole new element.
Physicists working at the Brookhaven National Lab's Relativistic Heavy Ion Collider (RHIC) are exploring the puzzle of proton spin as they begin taking data during the 2009 RHIC run.
They bombarded a proton target with polarized, heavy hydrogen nuclei known as deuterons.
Higher energy particles — such as those from the nuclei of heavy elements like iron — are rarer than common, lower - energy particles such as protons.
The second instrument is the Intergrated Science Investigation of the Sun which will measure energetic electrons, protons and heavy ions as they are accelerated in the corona.
«As already mentioned, there is no stable nucleus with five or eight nuclear particles [nucleons], so it is not possible to build nuclei heavier than helium by adding neutrons or protons to helium (4He) nuclei, or by fusing pairs of helium nuclei.
The vibrations that are set up temporarily distort a nucleus and, as explained on page 401, can cause it to eject one or more neutrons.83 The nucleus then becomes proton heavy which makes it less stable and more likely to decay.
As its name implies, this process must occur rapidly in order to build up to very heavy, neutron - rich nuclei that then decay into heavy elements, such as uranium, which has 92 protons compared to iron's 2As its name implies, this process must occur rapidly in order to build up to very heavy, neutron - rich nuclei that then decay into heavy elements, such as uranium, which has 92 protons compared to iron's 2as uranium, which has 92 protons compared to iron's 26.
Cosmic rays are specifically defined as high speed atomic nuclei, mostly protons and alpha particles, but other heavier particles can be found as well.
