SWS and LWS observations of Cassiopeia AThe observations of the Casssiopeia A supernova remnant performed with the short wavelength spectrometer (SWS) and the long wavelength spectrometer (LWS), onboard the Infrared Space Observatory (ISO), are reported on. Broad O III 52 micrometer and 88 micrometer and O I 63 micrometer emission lines were detected. The far infrared O III lines fit the model of a spherical shell with central velocity redshifted by 770 +/- 40 km/s. A pronounced density contrast between the front and back of the shell was detected.
