Does a BEC still have a very large refractive index for X Ray's and gamma rays?

The refractive index of a Bose-Einstein Condensate (BEC) for X-rays and gamma rays is primarily determined by electron density. Due to the low density of BECs, their refractive index is expected to be very close to 1, similar to other gases. This indicates that BECs do not exhibit a significantly large refractive index for these high-energy photons. The discussion emphasizes the relationship between electron density and refractive index in the context of BECs. Overall, BECs may not provide the desired optical properties for X-rays and gamma rays.
I am observing an irregular, aperiodic noise pattern in the reflection signal of a high-finesse optical cavity (finesse ≈ 20,000). The cavity is normally operated using a standard Pound–Drever–Hall (PDH) locking configuration, where an EOM provides phase modulation.
The signals shown in the attached figures were recorded with the modulation turned off. Under these conditions, when scanning the laser frequency across a cavity resonance, I expected to observe a simple reflection dip. Instead...
