In science:

Strong dependence of the transition frequency on Z allows only a few opportunities for a spectrum of two-body atoms with Z 6= 1 and/or m 6= me . • In contrast, a number of transitions in neutral atoms Z = 1 are suited for laser spectroscopy.
Precision physics of simple atoms: QED tests, nuclear structure and fundamental constants
One can also consider more complex configurations of spin imbalance where the number of atoms in the two spin states is different (N↑ 6= N↓ ) as well as mixtures of atomic species with different masses (m↑ 6= m↓ ), including Fermi-Fermi and Bose-Fermi mixtures.
Theory of ultracold Fermi gases
We can also conclude, that the intensity of the peaks is determined by the number of C atoms in the chain which is confirmed by comparing the intensities of the C8 and the C7 chains in Fig. 6.
Ab initio investigation of the groundstate, electronic, and optical properties of polyyne and cumulene prototypes
Equation (10) predicts that α 6= 0 due to contributions from the Coulomb and surface terms, whose relevance increases as the differences between the mass and/or the atomic numbers of the sources become larger.
Temperature effects in the nuclear isoscaling
The binding energy per nucleon is maximized for nucleons bound as a Fe nucleus. 6 These masses may be either nuclear masses or atomic masses, the electron number is conserved, and their binding energies are negligible, in comparison.
Introduction to Astronomy with Radioactivity
The number of Rydberg atoms in each sample obeys a Poisson statistics, with 0.6 atoms per sample on the average.
Real-time quantum feedback prepares and stabilizes photon number states
In a given host semiconductor, the energetic positions of CFR and DBH vary in a universal way with the atomic number of the TM [6, 9, 10, 11].

Let ϕ6= be the formula obtained from ϕ by deleting all inequalities, i.e. all atomic subformulas of the form x = y that occur in the scope of an odd number of negation symbols.
Fixed-parameter tractability, definability, and model checking
Fig. 6 confirms the onion shell model with the dominant elements ordered in shells following their atomic number (Stadlbauer & Aschenbach, 2001).
X-rays from Supernova Remnants
As shown in Fig. 19, this rank ordering of the observation probability of fragments of a given atomic number, from the largest to the smallest, does indeed lead to a Zipf ’s power law parameter λ = 1 in the 5-6 MeV/nucleon range.
Moment Analysis and Zipf Law
The same chemical characteristics can be expected for atoms with a fixed number of protons and with different number of neutrons and the energy in chemical reactions is of the order of 1 eV (1.6 × 10−19 Joule).

The number of Xe atoms/ kg is 0.267 / ton / y for M = 1010 GeV . The rate would be lower by a factor of 1.6 × 10 −7 if 5 × 1011GeV suggested by Simet et al. was used.
The experimental challenge of detecting solar axion-like particles to test cosmological ALP-photon oscillation hypothesis
For triangular dots there is a sublattice imbalance, i.e., NZ =NA − NB 6=0, where NA (NB ) is the number of carbon atoms of sublattice A (B ), and this condition is sufficient in order to have NZ zero-energy states [124].
