Abstract
We have measured the complex conductivity sigma of a Bi2Sr2CaCu2O8+delta th in film between 0.2 and 0.8 THz. We find sigma in the superconducting state to be well described as the sum of contributions from quasiparticles, cond ensate, and order parameter fluctuations which draw 30% of the spectral wei ght from decomposition yields a quasiparticle scattering rate on the the co ndensate. Hn analysts based on this order of k(B)T/h for temperatures below T-c.
