Um hartree (símbolo E h) é a unidade atômica de energia. Cálculos da estrutura atômica. Em 1921, uma visita de Niels Bohr a Cambridge inspirou Hartree a aplicar suas habilidades numéricas à teoria do átomo de Bohr, pela qual obteve seu Ph.D. em 1926 – seu orientador foi Ernest Rutherford.
Douglas Rayner Hartree FRS (27 March 1897 – 12 February 1958) was an English mathematician and physicist most famous for the development of numerical analysis and its application to the Hartree–Fock equations of atomic physics and the construction of a differential analyser using Meccano.
Um Hartree (símbolo E h) é a unidade atômica de energia, chamada assim pelo físico Douglas Hartree. A energia de Hartree é igual ao valor absoluto da energia potencial elétrica do átomo de hidrogênio em seu estado fundamental.

1 de mai. de 2024 · Douglas R. Hartree was an English physicist, mathematician, and computer pioneer. At Manchester University in the mid-1930s, he built a mechanical computer for solving differential equations, based on the differential analyzer of Vannevar Bush. During World War II he was involved with the ENIAC.
The hartree (symbol: E h), also known as the Hartree energy, is the unit of energy in the atomic units system, named after the British physicist Douglas Hartree. Its CODATA recommended value is E h = 4.359 744 722 2060 (48) × 10 −18 J = 27.211 386 245 981 (30) eV.
