| Abstract: | We analyze the problem of infrared optical absorption in a clean layered London superconductor in the vicinity of the gap  =2 . We conclude that absorption of light with wave vectorq c is enhanced over ordinary Drude absorption (q c) due to resonance absorption (Landau damping). Experimental absorption studies with qc might therefore improve chances to observe a superconducting gap in the high-T
