Alpha Particle X-ray Spectrometer - Protons
... The process produces protons of a defined energy which are detected ... For the Mars Exploration Rovers the proton detector was replaced by a second alpha particle sensor ...
Atomic Nucleus - Forces
... is a minor residuum of the strong interaction which binds quarks together to form protons and neutrons ... This force is much weaker between neutrons and protons because it is mostly neutralized within them, in the same way that electromagnetic forces between neutral atoms (such as van der Waals forces that ... and this overwhelms the repulsion between protons which is due to the electromagnetic force, thus allowing nuclei to exist ...
Atomic Nucleus - Protons and Neutrons
... Protons and neutrons are fermions, with different values of the strong isospin quantum number, so two protons and two neutrons can share the same space wave function since they are not identical quantum ... Two fermions, such as two protons, or two neutrons, or a proton + neutron (the deuteron) can exhibit bosonic behavior when they become loosely bound in ... The proton has an approximately exponentially decaying positive charge distribution with a mean square radius of about 0.8 fm ...
LHC - Operational History - Inaugural Tests
... CERN successfully fired the protons around the tunnel in stages, three kilometres at a time ... runs, two white dots flashed on a computer screen showing the protons travelled the full length of the collider ... CERN next successfully sent a beam of protons in a counterclockwise direction, taking slightly longer at one and a half hours due to a problem with the cryogenics, with the full ...
Sequential Walking
... Each nucleotide has protons on the deoxyribose sugar, which can be assigned using sequential walking. 2' and 2" protons of a nucleotide will show up in its column, as well as in the column of the next nucleotide in the sequence ... in the sequence CATG, in the column for C, its own 2' and 2" protons will be seen, but none of the other nucleotides ...
