WebAbstract:For dealing with atoms involving many electrons the accurate quantum theory, involving a solution of the wave equation in many-dimensional space, is far too complicated to be practicable. One must therefore resort to approximate methods. The best of these is Hartree's method of the self-consistent field.

It is found that the imposition of Hermitian symmetry upon the single particle Thomas‐Fermi density matrix changes the single particle exchange energy density operator in … sharp healthcare ethicsWebNote on Exchange Phenomena in the Thomas Atom.
