binding energyEnergy required to separate a particle from a system of particles or to disperse all the particles of a system. Nuclear binding energy is the energy required to separate an atomic nucleus into its constituent protons and neutrons. It is also the energy that would be released by combining individual protons and neutrons into a single nucleus. Electron binding energy, or ionization potential, is the energy required to remove an electron from an atom, molecule, or ion, and also the energy released when an electron joins an atom, molecule, or ion. The binding energy of a single proton or neutron in a nucleus is about a million times greater than that of a single electron in an atom. |

Binding energy of the hydrocarbon component peak at 285 eV was used as a reference. The PWB cross sections are calculated from uncorrelated wave functions, and the scaling requires only the binding energy B of the bound electron that is excited, the excitation energy E, and an accurate dipole oscillator strength f for the transition. For example, the binding energy of the extra electron in a negatively charged calcium ion is sufficiently low that the ions measured lifetime of 490 microseconds is determined almost entirely by environmental blackbody radiation. |
