A preliminary COMPTEL Cosmic Diffuse Gamma-Ray (CDG) spectrum from 800
keV to 30 MeV was presented earlier at the 3rd Compton Symposium. The
COMPTEL results represent the first significant detection of the CDG
radiation in the 9 to 30 MeV range. Using high-latitude data from the
first 5 years of the mission we have performed a new detailed
measurement of the 9 to 30 MeV spectrum with finer energy binning. The
new improved results are in good agreement with our previous estimates
and are compatible with power-law extrapolations from higher
energies. The measured 9-30 MeV spectra from the Virgo and South
Galactic Pole observations are consistent with each other.
