... Bringing a charged particle from nearly at rest to high energy requires that it be sufficiently stable to not decay in flight. The particles must exist in sufficient abundance to give high intensity beams (the collision processes are rare). This limits the available particles to electrons and posi ...

... Ask class: if you crush the Sun down to a radius 1000 times less than it actually has, what happens to the optical depth to neutrinos? Density is 10003 = 109 times greater, but the length traveled is 1000 times less, so optical depth is 106 times greater. That suggests an optical depth of about 10−3 ...

Thus, if the average interparticle distance is l - N- 1/ 3 , where N is the number of electrons per unit volume, the applicability of the "refractive index" concept will impose on the photon energy a limit: w ~ 1 ~ N113 , whence it follows that ...

Answer: In neutron stars. A neutron star is formed at the end of the life of a massive star. The pull of gravity is so st ...

Gets better with more energy since there is more secondary electrons and photons to sample. e) Hadrons will interact strongly in dense matter such as iron and the energy of the resulting particles can be measured. Muons will go through without much interacti ...
