Abstract:
Grating spectra, covering the wavelength range 45 to 
m have been taken
with the ISO Long Wavelength Spectrometer (LWS) at a series of pointing
positions over the S140 region, centred on the cluster of embedded young
stellar objects at the south-west corner of the L1204 molecular cloud.
Extended emission from [CII] 
m and [OI] 
m is seen, peaking near
the
position of the embedded stars. The measurements of the fine structure
lines are
interpreted in terms of PDR models for the emission, as well as the
underlying thermal continuum for the heated gas and dust.
