Hartree energy

The Hartree energy (symbol Eh) is a physical constant used as atomic unit of energy, named after physicist Douglas Hartree.

It has a value of twice the absolute value of binding energy of the electron in the ground state of the hydrogen atom |W1| or the ionization energy.

= 4.359 743 81(34) × 10-18 J = 27,214 4 eV = 2 Ry

where:

is the Dirac's constant,
is the electron rest mass
is the Bohr radius
