Kiloelectron-Volt
A kiloelectron-volt (keV) is a unit of energy equal to 1,000 electron-volts, commonly used in atomic and nuclear physics to measure small amounts of energy.
History/Origin
The electron-volt was introduced in the early 20th century as a convenient unit for expressing energies at the atomic scale, with the prefix 'kilo' added later to denote 1,000 electron-volts, especially in high-energy physics and astrophysics.
Current Use
The keV is widely used today in fields such as X-ray spectroscopy, astrophysics, and particle physics to quantify energies of particles, photons, and nuclear processes.
Hartree Energy
The Hartree energy (Eh) is a unit of energy used in atomic physics, representing the total energy of an electron in a hydrogen atom in its ground state.
History/Origin
Named after the American physicist Douglas Hartree, the Hartree energy was introduced in the early 20th century as a fundamental atomic unit of energy within the system of atomic units, facilitating calculations in quantum mechanics.
Current Use
The Hartree energy is primarily used in theoretical and computational chemistry and physics to express energies at the atomic and molecular scale, especially in quantum chemistry calculations and atomic physics research.
