This will usually be SI, but not always; for example, theoretical chemists commonly use atomic units, natural units, Debyes, etc.
12.
The electricity generated by the atomic units will be replaced by restarting old power plants fired by much dirtier coal and oil.
13.
Hamiltonian H for relativistic electron moving in the Coulomb potential can be chosen in the following form ( atomic units are used ):
14.
The same holds true for the United States, where there are 109 atomic units, more than in any other country, but none under construction.
15.
A related early idea was Prout's hypothesis, formulated by English chemist William Prout, who proposed that the hydrogen atom was the fundamental atomic unit.
16.
This number describes the wavelength of light, in atomic units, required to induce a transition from beta-carotene's ground state to its first excited state.
17.
The atomic unit of mass is by definition " one twelfth of the rest mass of an unbound atom of carbon-12 in its nuclear and electronic ground state ".
18.
In the Bohr model of the atom, the energy of a state with principal quantum number n is given in atomic units as E =-1 / n ^ 2.
19.
Additionally, the scheduler uses nanosecond granularity accounting, the atomic units by which an individual process'share of the CPU was allocated ( thus making redundant the previous notion of timeslices ).
20.
The kinetic energy of an electron in a single-particle state can be written exactly in terms of the orbital, | \ phi _ i \ rangle, as ( in atomic units)
