The nuclear magnetic moment μ, often represented by the g-factor g=|μ|/IμN, is an excellent probe for the single-particle structure of the nucleus [12]. Close to a magic number, magnetic dipole moments are expected to be relatively close to the single-particle expectation value, the ...
[16]. The CCS measurements for these oligomers indicated a sheet-like structure, in comparison with the less compact measurements obtained for a range ofglobular proteinsof similar molecular mass. From these data, the authors proposed that the capsid assembly process begins with a nucleus exhibiting...
It represents the number of protons in the atom's nucleus. The number below the symbol is the atomic mass, which is the weight of the atom; this is the sum of the number of protons and neutrons. For example, hydrogen, the first element in the periodic table, has an atomic number of...
atomic mass,the mass of a singleatom, usually expressed inatomic mass units(amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass is always very close to themass number...

(eq 4) where σpe is the atomic photoeffect cross section, σcoh and σincoh are the coherent (Rayleigh) and the incoherent (Compton) scattering cross sections, respectively, σpair and σtrip are the cross sections for electron-positron production in the fields of the nucleus and of the ...
which achieves relative mass uncertainties of the order of 10−11. However, redundancy checks using data from different experiments reveal considerable inconsistencies in the masses of the proton, the deuteron and the helion (the nucleus of helium-3), suggesting that the uncertainty of these values...
