Web13 feb. 2014 · Hi, this probably has been answered somewhere here already, but I was unable to find it. Could someone explain how the spin of a particle is actually measured in an experiment ? Most interesting to me is how the 3d spin vector for 1/2 spin particles is determined experimentally. Cheers.

WebSpin has no analogue in classical physics, but it can be thought of as a kind of angular momentum. When an object is charged and has an angular momentum, it will be … Spin is described mathematically as a vector for some particles such as photons, and as spinors and bispinors for other particles such as electrons. Spinors and bispinors behave similarly to vectors: they have definite magnitudes and change under rotations; however, they use an unconventional … Meer weergeven Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nuclei. Spin is one of two types of angular momentum … Meer weergeven As the name suggests, spin was originally conceived as the rotation of a particle around some axis. While the question of whether … Meer weergeven In ordinary materials, the magnetic dipole moments of individual atoms produce magnetic fields that cancel one another, because each dipole points in a random direction, … Meer weergeven Operator Spin obeys commutation relations analogous to those of the orbital angular momentum: $${\displaystyle \left[{\hat {S}}_{j},{\hat {S}}_{k}\right]=i\hbar \varepsilon _{jkl}{\hat {S}}_{l},}$$ Meer weergeven Particles with spin can possess a magnetic dipole moment, just like a rotating electrically charged body in classical electrodynamics. These magnetic moments … Meer weergeven Spin projection quantum number and multiplicity In classical mechanics, the angular momentum of a particle possesses not only a magnitude (how fast the body is rotating), but also a direction (either up or down on the Meer weergeven In tables of the spin quantum number s for nuclei or particles, the spin is often followed by a "+" or "−". This refers to the parity with "+" for even parity (wave function unchanged by spatial inversion) and "−" for odd parity (wave function negated by … Meer weergeven design your own balaclava
