Refractive index of BEC

  1. Feb 10, 2016 #1
    Does a BEC still have a very large refractive index for X Ray's and gamma rays?

    The refractive index for x-rays and gamma rays depends essentially only on the electron density. As BECs are just very cold gasses with a not so high density, the refractive index will be very close to 1, just as for any other gas.
