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.
Megaelectron-Volt
A megaelectron-volt (MeV) is a unit of energy equal to one million electron-volts, commonly used in nuclear and particle physics to express the energy of particles.
History/Origin
The megaelectron-volt was introduced as a convenient unit for expressing high-energy particles in physics, particularly after the development of particle accelerators in the mid-20th century, replacing the electron-volt for larger energy scales.
Current Use
Today, the MeV is widely used in nuclear physics, particle physics, and astrophysics to quantify the energy of subatomic particles, nuclear reactions, and cosmic phenomena.
