Atom center of mass, although strictly speaking these particles are believed to be point-like and cannot be said to be rotating. Spin is measured in units of the reduced Planck constant (ħ), with electrons, protons and neutrons all having spin ½ ħ, or "spin-½". In an atom, electrons in motion around the nucleus possess orbital angular momentum in addition to their spin, while the nucleus itself possesses angular momentum due to its nuclear spin. The magnetic field produced by an atom—its magnetic moment—is determined by these various forms of angular momentum, just as a rotating charged object classically produces a magnetic
Olaf—An Atom he recovers, alone and forgotten by those he has helped. He then moves aimlessly along. Directed by Anthony O'Sullivan and written by William E. Wing, "Olaf—An Atom" was produced by the Biograph Company and released May 19, 1913, in the United States. The drama was released August 4, 1913, in the United Kingdom. The film was retitled "The Wanderer" and re-released by the Aywon Film Corporation, a New York City company formed in early 1919. Aywon reissued films including the Biograph Company short films, which were often lengthened by the addition of intertitles. Olaf—An Atom Olaf—An Atom is a 1913
