Spin Rotation: The Tin Isotopes, PhD thesis, Harvard University, 1981.
An axial magnetic field will rotate a transverse
spin vector about the momentum axis.
The magnetic strength of a nucleus is only about one six-hundredth that of an electron's
spin.
Among specific results reported in the monographs: Watson derives equations for calculating yo-yo rotation rates after free fall or a hard throw; he analyzes features of yo-yo strings and investigates why yo-yos wobble; and he discovers a "yo-yo constant" that links yo-yo
spin speeds to the rotational property known as the radius of gyration.
The experimental setup and the
spin component behaviours are shown in Fig.

spin filter (NSF) and gives basic information.
To arrive at the new findings, the experimenters made a target of helium gas in which nearly all atoms were forced to
spin in the same direction and bombarded it with a beam of high-energy electrons, whose
spins were also forced to have uniform orientations.
1]) is the angular precession rate of the neutron
spin in a magnetic field.
However, the
spin currents enhanced each other because they were of opposite polarity and direction, van Driel says.
With the help of a laser, the team next produced within the microstructure many electrons with the same
spin orientation.
12] cm, [tau] and M are unit vectors in the direction of the reciprocal lattice vector [tau] and the
spin direction, respectively, and the orientation factor <1-[([tau] * M).
