Helium atom −54.41776311(2) eV. The total ground state energy of the helium atom is −79.005151042(40) eV, or −2.90338583(13) a.u. Helium atom A helium atom is an atom of the chemical element helium. Helium is composed of two electrons bound by the electromagnetic force to a nucleus containing two protons along with either one or two neutrons, depending on the isotope, held together by the strong force. Unlike for hydrogen, a closed-form solution to the Schrödinger equation for the helium atom has not been found. However, various approximations, such as the Hartree–Fock method, can be used to estimate the ground state energy and
The Atom Station of an atom station in Iceland. After a short relationship with Búi Árland, Ugla decides to return to the “selfconscious policeman”, who is the father of her recently born child. "The Atom Station", written in 1946 and 1947, was published in 1948. The historical background of the novel is the British and later American occupation of Iceland during World War II, including the urbanisation and monetization of the Icelandic economy it stimulated. Many viewed Iceland’s independence as threatened due to the United States’ request in 1946 to establish a military base in Keflavík for 99 years, and pressure on Iceland
