From the Einstein equation, E = mc2, which is discussed further in Chapters 4 and 12, one can calculate that one atomic mass unit is equivalent to 931.5 MeV, where MeV is a million electron volts. (3.3)E=mc2=931.5 ΔMA The relationship of energy and mass would indicate that in...
Since the discovery of neutrino oscillations, we know that neutrinos have non-zero mass. However, the absolute neutrino-mass scale remains unknown. Here we report the upper limits on effective electron anti-neutrino mass, mν, from the second physics run
The researchers had managed a spectacular discovery: a particle with a mass of 125 GeV / c². GeV stands for " gigaelectronvolts " - or a billion electronvolts - and GeV / c² is a unit of mass used in elementary particle physics. www.bmbf.de Am 4. Juli 2012 veröffentlichte...
Radioactive atoms were produced by nuclear reactions of 1.4 GeV protons impinging on a thick lanthanum carbide target. Short-lived indium atoms diffusing from the target were selectively ionized using a two-step laser excitation scheme, provided by the ISOLDE RILIS, which excited one electron abov...
In this case the units for length and time are equal and inverse to the unit of mass. The only independent quantity is (3), which has dimension of energy and can be measured in electron-volts : An exact definition of the Planck mass does not make big sense, because the dimensional ...

How fast must an electron move so that its total energy is 32% more than its rest mass energy? Relativistic Energy Everyone is familiar with Einstein's famous equation {eq}E = m c^2 {/eq}. The energy in this case is the total energy of an object, i...
Charged-particle kinetic energy can be expressed in electron volts, so the voltage driving a charged particle current in a charging circuit model is the same as the charged-particle kinetic energy expressed in electron volts (Smirnov, 2001; Lieberman & Lichtenberg, 1994). Processes driving space...
The energy spread of ions desorbing from a surface is severalelectron volts, which causes uncertainty in the mass determination. To compensate for the energy spread, two instrument designs are generally used. The first is the high-performance ‘reflectron’ TOF configuration and is commercially ava...
