It...&quot;</p> <p><b>New page</b></p><div>This page is a work in progress by --[[User:Hjohnston7|Hjohnston7]] ([[User talk:Hjohnston7|talk]]) 15:27, 28 October 2015 (EDT)<br /> == Overview ==<br /> <br /> Spin is an intrinsic property that is carried by all elementary particles, composite particles, and atomic nuclei. It is a form of angular momentum, the other form being orbital angular momentum. It has never been observed directly, but is has been inferred from experimental data, namely the Stern-Gerlach Experiment.<br /> <br /> Spin is usually thought of as a particle rotating about its own axis. This idea was proposed by Ralph Kronig, George Uhlenbeck, and Samuel Goudsmit and later expanded on by Wolfgang Pauli.<br /> <br /> <br /> == Properties ==<br /> <br /> &#039;&#039;&#039;Spin Quantum Number&#039;&#039;&#039;<br /> <br /> The quantum spin number is a number that describes properties about the quantum spin. It is a positive number that is determined by s = n/2, with n being any non-negative number.<br /> <br /> &#039;&#039;&#039;Madnitude&#039;&#039;&#039;<br /> <br /> Since spin is a vector quantity, it has both a magnitude and a direction. All similar elementary particles have the same magnitude of spin angular momentum which is given by the spin quantum number, Ms. The quantum spin number is usually represented as a unitless value. This is due to the fact that is is expressed as a multiple of the Planck Constant. The actual unit of spin is the Joule-second.<br /> <br /> &#039;&#039;&#039;Direction&#039;&#039;&#039;<br /> <br /> Due to its quantum nature, it is difficult to measure the direction of spin. Actually, when measuring spin around the x-axis, spin information on the y and z-axes is destroyed. Therefore, it is easier to describe the direction more abstractly.<br /> <br /> All possible spin directions are described by the expression &quot;2s+1.&quot;<br /> <br /> For a spin-1/2 particle, the amount of all possible directions is 2. These directions are -1/2 and 1/2. These states are described as &quot;spin-up&quot; and &quot;spin-down.&quot; <br /> <br /> For a spin-3/2 particle, the amount of possible directions is 4. These directions are -3/2, -1/2, 1/2, and 3/2.</div>
