Hartree

The Hartree energy ( after the English physicist Douglas Rayner Hartree ) is a physical constant that is used in atomic units as the unit of energy:

With

  • The Planck constant
  • The rest mass of the electron
  • The Bohr radius
  • The elementary charge
  • The electric field constant
  • The speed of light
  • The fine structure constant.

The Hartree energy is twice the value of the binding energy of the electron in Ry ground state of the hydrogen atom:

Where the numbers in parenthesis the estimated uncertainty ( 1 standard deviation) specify for the mean and refer to the last two decimal digits specified.
