We report an infrared reflectivity study of epitaxial YBa2Cu307-6 thin films. Results for samples with different values of To, obtained by Fe doping or ion bombardment, give evidence for a gap 2A(0) ~ 7 kBTc. For ion bombarded films we find a soft mode that may correspond to a giant-amplitude oxygen

We report on the far-infrared reflectivity and absorptivity of high quality YBa2Cu307\_b thin films. The absorptivity can be characterized by three contributions: free carriers absorption that disappears below T e , an absorption process that sets in near 400 cm-I (21::1/kBT e ;::j 6) and is almost
