Helium atom
is just the sum of the two hydrogenic Hamiltonians:
where
, the energy eigenvalues and , the corresponding eigenfunctions of the hydrogenic Hamiltonian function will reduce to the 'zero-order' equation
This equation is separable and the eigenfunctions can be written in the form of single products of hydrogenic

Ferromanganese nodules
Nodule formation in oxic waters at or below the carbonate compensation depth produces the most desirable rare metal ratio in hydrogenic nodules. However, the low estimated growth rate of hydrogenic nodules of about 2-5 mm per million years categorizes them as a non-renewable resource.

Quantum defect
In hydrogenic atoms
The quantum defect of an alkali atom refers to a correction to the energy levels predicted by the classic calculation of the hydrogen experienced by the single valence electron of an alkali atom is that the ionic core acts as a point charge with effective charge e and the wavefunctions are hydrogenic

Heavy Rydberg system
The peculiar properties of the Rydberg atom come from the large charge separation and the resulting hydrogenic potential. The extremely large separation between the two components of a heavy Rydberg system results in an almost perfect 1/r hydrogenic potential seen by each
