In science:

These are: a) A one amu (atomic mass unit) mass separation for light nuclei over a broad momentum range extending from about 1 GeV/c per nucleon, up to around 13 GeV/c per nucleon at best, for mass numbers A≈20.
Experimental study of a proximity focusing Cherenkov counter prototype for the AMS experiment
However the total number of spins must be small as the τ0 obtained from the dynamical scaling is atomic-like (∼ 10−13 s).
The nanoscale phase separation in hole-doped manganites
With the increase of C o amount, the E high 2 mode shows a red shift up to ∼ 1.2 cm−1 and broadens up to ∼ 13 cm−1 due to disorder effects in the oxygen sublattice (vacancies, interstitials) inducing a change in coordination numbers of some C o atoms due to oxygen vacancies.
Ferromagnetism in Co-doped ZnO films grown by molecular beam epitaxy: magnetic, electrical and microstructural studies
The effective phonon number given by Eqn. (25) is shown in Fig.13(b) as a function of dimensionless detuning (∆d /ωm ) for the absence of BEC (thick solid line) and the three different values of atom-atom interaction, Uef f = 0.4ωm(dashed line), Uef f = 0.8ωm(thin solid line) and Uef f = 1ωm(dot dashed line).
Achieving the Quantum Ground State of a Mechanical Oscillator using a Bose-Einstein Condensate with Back-Action and Cold Damping feedback schemes
At the outer side, left and right, it is designated the number of atoms within coding codons; more exactly, in the Py-Pu bases (U = 12, C = 13, A = 15 and G = 16); at the inner side – the atom number within amino acid side chains.
