atomic physicsScientific study of the structure of the atom, its energy states, and its interaction with other particles and fields. The modern understanding of the atom is that it consists of a heavy nucleus of positive charge surrounded by a cloud of light, negatively charged electrons. The physical properties of atoms are largely determined by the laws of quantum mechanics and quantum electrodynamics. The primary tools for the study of these properties are spectroscopy, particle collisions (see particle accelerator), and statistical models that simulate complex, many-body interactions (such as gas dynamics). A broad field, atomic physics has applications in the study of condensed matter, gases, chemical-reaction mechanisms, atmospheric science, lasers, nuclear physics, and the arrangement of elements in the periodic table. |

The standard magnetic trap of the Ioffe-Pritchard type that is widely used in atomic physics consists of a magnetic quadruple with two solenoids at its edges. Post-Hiroshima atomic physics captured his soaring imagination, too, producing giant, sky-bound heads that explode in a whirlwind of infinite particles. in atomic physics from the University of Chicago, life is a series of smashing electrons. |
