Expressing and Measureing of Photon's Spin Weight
Xing Li · Journal of Hubei Institute for Nationalities · 2005
At first we described the eigenvalue and eigenvector of photon's spin weight along any direction. Then as to two vertical direction to each other, to measure the second direction spin weight at the eigenstate of the first direction spin weight, we discussed the method of obtaining the probability of eigenvalue of it, and used income result to work out the probability of spin weight of particle by using Stern-Gerlach experiment device.
