Abstract
We have combined all OSSE spectra of the Orion molecular cloud complex obtained through the end of 1996 and searched them for evidence of co smic-ray induced gamma-ray lines in the 3-7 MeV energy range, as detec ted by COMPTEL (Bloemen et al. 1994, 1997). We do not detect any signi ficant line emission; our flux estimate for broad-line emission of 1.5 +/- 1.0 10(-4) gamma/(cm(2)-s) is consistent with the spatially-exten ded flux 1.3 10(-4) gamma/(cm(2)-s) measured by Bloemen et al. (1997).
