Photons from heavy-ion collisions at Fermi velocity.
The production of photons from heavy-ion collisions at intermediate energies is studied in the model based on the Boltzmann-Uehling-Uhlenbeck equation. Taking into account photon production from nucleon-nucleon collisions, the theoretical results are in reasonable agreement with the experimental data at 40 MeV/nucleon, but cross sections are smaller by about a factor of 5, compared to experimen...
متن کاملProof That the Velocity of Photons Is Not Constant but Varies
It has been tried to prove: 1. Since the electrons possess spin motion, the photons emitted from the orbiting electrons too possess spin motion and their velocity depends upon frequency of their spin motion (ph w) and frequency of spin motion of the orbiting electrons (w); 2. The velocity of photons of infrared, visible, ultraviolet and higher frequency regions also depends upon their ph w. The...
متن کاملQuantum Mechanical Relations for the Energy, Momentum and Velocity of Single Photons
The refraction of light as it passes through transparent media is a phenomenon of everyday experience which has occupied the attention of scientists dating back at least to the time of the ancient Greek philosophers . Since the experiments of Foucault in 1850, it has been known that light moves more slowly in water and other materials than it does in free space . Newton [1] and his followers ha...
متن کاملProof That the Velocity of Photons Cannot Be Constant but Should Vary
It has been tried to prove: 1. The photons possess rest mass; 2. Since the electrons possess spin motion, the photons emitted from the orbiting electrons too should possess spin motion and their (photons) velocity should depend upon frequency of their spin motion ( ph w ); 3. The velocity of photons of infrared, visible, ultraviolet and higher frequency regions should also depend upon their ph ...
متن کاملExponentiation of soft photons in a process involving hard photons.
We present a simple method of removing the singularities associated with soft photon emission to all orders in perturbation theory through exponentiation, while keeping a consistent description of hard photon emission. We apply this method to the process e + e ? ! + ? + n where we include both Z 0 and exchange and retain the muon mass dependence. The photonic radiation is allowed to be radiated...
