"Atomic physics is the field of physics that studies atoms as an isolated system of electrons and an atomic nucleus."
The study of the behavior and properties of atoms, including the structure of the nucleus and the interactions of atoms with electromagnetic radiation.
Quantum Mechanics: The study of the behavior of matter and energy at the nanoscale level.
Atomic Structure: The arrangement of electrons, protons, and neutrons in an atom.
Nuclear Structure: The composition and behavior of atomic nuclei.
The Photoelectric Effect: The emission of electrons from a material when light is shone on it.
Black-body Radiation: The energy emitted by a heated object, usually in the form of light.
X-ray Diffraction: The scattering of X-rays by crystal structures, used to determine the arrangement of atoms in solids.
Subatomic Particles: The properties and behavior of protons, neutrons, and other subatomic particles.
Radioactivity: The spontaneous decay of unstable atomic nuclei.
Nuclear Reactions: The processes by which atomic nuclei change with the release of energy.
Quantum Electrodynamics: The study of the interactions between electromagnetic radiation (light) and matter.
Atomic Spectra: The properties of light emitted or absorbed by atoms, used to analyze the composition of matter.
Quantum Field Theory: The mathematical framework used to describe the behavior of subatomic particles.
Particle Physics: The study of fundamental particles and their interactions.
Relativity: The theory of space, time, and gravity developed by Albert Einstein.
Cosmology: The study of the origin, evolution, and structure of the universe.
Atomic structure: The study of electrons and the nucleus in atoms, including the energy levels and transitions between them.
Quantum mechanics: The branch of atomic physics that deals with the behavior of particles on the atomic scale, where classical mechanics no longer applies.
Nuclear physics: The study of the nucleus and its interactions with other particles, including the properties of radioactive decay.
Particle physics: The study of the fundamental particles and their interactions, including the search for new particles and the determination of their properties.
Condensed matter physics: The study of materials with large numbers of atoms or particles, including the properties of solids, liquids, and gases.
Plasma physics: The study of the behavior of ionized gases, including fusion reactions and space plasma.
Atomic spectroscopy: The study of the interaction between light and matter at the atomic level, including applications in chemistry and astrophysics.
Quantum optics: The study of the behavior of light and its interactions with matter at the quantum level, including applications in communications and computing.
Molecular physics: The study of the structure and properties of molecules, including their interactions with light and other particles.
Astrophysics: The study of the behavior of matter and energy in the universe, including the structure and evolution of stars and galaxies.
"Atomic physics typically refers to the study of atomic structure and the interaction between atoms."
"It is primarily concerned with the way in which electrons are arranged around the nucleus and the processes by which these arrangements change."
"Unless otherwise stated, it can be assumed that the term atom includes ions."
"The term atomic physics can be associated with nuclear power and nuclear weapons, due to the synonymous use of atomic and nuclear in standard English."
"Physicists distinguish between atomic physics—which deals with the atom as a system consisting of a nucleus and electrons—and nuclear physics, which studies nuclear reactions and special properties of atomic nuclei."
"As with many scientific fields, strict delineation can be highly contrived and atomic physics is often considered in the wider context of atomic, molecular, and optical physics."
"This comprises ions, neutral atoms and, unless otherwise stated, it can be assumed that the term atom includes ions."
"Physics research groups are usually classified into atomic, molecular, and optical physics."
