WebJun 18, 2015 · 1 Answer. "Spin" is dictated by the representation of the Loretz group the field the particle is a quantum of transforms in. Half-integer spins are fermions, integer spins are bosons by the spin-statistics theorem, where representations of the Lorentz group are labeled by two numbers ( s 1, s 2), whose sum is what we call spin in this context. WebIt is an empirical question whether photons always obey Bose-Einstein statistics, but devising and interpreting experimental tests of photon statistics can be a challenge. The nonrelativistic cross section for Compton scattering illustrates how a small admixture ν of wrong-sign statistics leads to a loss of gauge invariance; there is a large anomalous …

Webfor photons of the same energy. This selection rule is re-lated to the fact that photons obey Bose-Einstein statistics. We have searched for small violations of this selection rule by studyingtransitions in atomic Ba. We set a limit on the prob-ability v that photons are in exchange-antisymmetric states: v<1:2 10−7. WebThe reason why two photons can have exactly the same frequency, phase and location in space is because they obey Bose-Einstein statistics. Photons have spin 1 which is why they are Bosons with Bose-Einstein statistics. If the photon were a fermion (like the spin 1/2 electron) simulated emission would not be possible since it is impossible for ... pashtoon kasi university of iowa https://matrixmechanical.net
