The hydrogenic power unit can be removed and re-assembled as a personal jet pack, or other devices of comparable size ( additional components for which are stored towards the back of the vehicle ).
12.
On the other hand, because the-reaction has only one reactant, its rate is twice as high as when the fuel is divided between two different hydrogenic species, thus creating a more efficient reaction.
13.
Assuming that the total pressure is fixed, this means that density of the non-hydrogenic ion is smaller than that of the hydrogenic ion by a factor 2 / ( " Z " + 1 ).

15.
The three exceptions to the definition of a Rydberg atom as an atom with a hydrogenic potential, have an alternative, quantum mechanical description that can be characterized by the additional term ( s ) in the atomic Hamiltonian:
16.
Since there are no known solutions for many-electron systems ( there "'are "'solutions for one-electron systems such as hydrogenic atoms and the diatomic hydrogen cation ), the problem is solved numerically.
17.
Additional terms in the potential energy expression for a Rydberg state, on top of the hydrogenic Coulomb potential energy require the introduction of a quantum defect, ? " l ", into the expression for the binding energy:
18.
E n i, the energy eigenvalues and \ psi _ { n _ i, l _ i, m _ i } ( \ vec { r } _ i ), the corresponding eigenfunctions of the hydrogenic Hamiltonian will denote the normalized energy eigenvalues and the normalized eigenfunctions.
19.
It's important to notice that this formula can be directly applied only to hydrogen-like, also called " hydrogenic " atoms of chemical elements, i . e . atoms with only one electron being affected by an effective nuclear charge ( which is easily estimated ).
20.
It can also be inferred from the spectra of antiprotonic helium atoms ( helium atoms where one of the electrons has been replaced by an antiproton ) or from measurements of the electron " g "-factor in the hydrogenic ions 12 C 5 + or 16 O 7 +.
