This idea of the importance of the square root of mass is of interest, we believe, inconnexion with the following facts concerning the relative masses of the proton, electron, and helium nucleus.doi:10.1038/124180a0WITMERENOS E.Nature

it's because an atom of carbon-12 has 12 nucleons, 6 protons plus 6 neutrons (and 6 electrons). So the atomic mass unit is the mass of one nucleon. Some luck helped here, as the mass of a neutron resembles the mass of a proton plus an electron. So in a neutral atom, protons+...
Hydrogen atom in crossed electric and magnetic fields: transition from weak to strong electron-proton decentring The hydrogen atom in crossed electric and magnetic fields is studied, taking full account of centre-of-mass effects and using a variational basis which does not depend on the choice of...
Relative Momentum of Quarks in Mesons at Center of Mass Frame When we study the bound state of quarks, i.e. mesons, the relative momentum is given as; q=1/2(p1-p2). Where p1 and 2, are momentum of quark and anti-quark, respectively.My question is, what is the value of q at ce...
Although some FLASH effects have been observed with photon24 and proton25 beams, the most established demonstrations were obtained using low-energy electron facilities (< 20 MeV), thus limiting their current potential application to superficial tumors. The use of VHEEs could address this...
Nuclear structure and beta decay (1932-1933) Before the discoveries of the neutron and the positron in 1932, the only known fundamental material particles were the electron and the proton (referred to... Brown,M Laurie - 《American Journal of Physics》 被引量: 4发表: 1988年 加载更多来源...
Kinetics of ferricyanide-mediated oxidation of various 1-(4-substituted phenyl)-1,4-dihydronicotinamides were studied assuming either a rate determining initial electron loss or a rate determining proton loss following a rapid pre-equilibrium step. Values obtained using both methods were similar. In ...
Electron BeamsPhoton BeamsWith aim to verify the validity of simulation with photon irradiators, of damage caused on internal containment coatings by beta plus gamma mixed fields following a LOCA in LWR, irradiation tests with Co 60 photons and with nearly 1.5 MeV mean energy electrons have been...
