When the American physicist Arthur Compton discovered that light waves behave like particles in 1922, and could knock electrons out of atoms during an impact experiment, it was a milestone for quantum mechanics. Five years ...

Nuclear fission is a process in which a heavy nucleus split into two. Most of the actinides nuclei (plutonium, uranium, curium, etc) fission asymmetrically with one big fragment and one small. Empirically, the heavy fragment ...

The nuclear force that holds protons and neutrons together in the center of atoms has a non-central component—the tensor force, which depends on the spin and relative position of the interacting particles.

The nucleus of thorium-229 possesses a property that is unique among all known nuclides: It should be possible to excite it with ultraviolet light. To date, little has been known about the low-energy state of the Th-229 nucleus ...

Atoms are composed of electrons moving around a central nucleus to which they are bound. The electrons can also be torn away via the powerful electric field of a laser, overcoming the confining force of their nucleus. A half-century ...

Last year, physicists at TU Darmstadt cast doubt on our current understanding of the interplay between electrons and atomic nuclei, and are now upping the ante by proposing a solution to this so-called "hyperfine puzzle." ...
