Abstract (C-13)O observations with 2.7 arcsec angular resolution were made of IRAS sources in L1641 to test the association of (C-13)O dense cores with young stellar objects. The sample includes 40 IRAS sources, eight of which are associated with CO molecular outflows, and the other 32 are randomly selected from an IRAS catalog by Strom et al. (1989). We find that six of eight outflow sources are associated with molecular dense cores, compared to only five of 32 nonoutflow sources. We also find that the cold IRAS sources, including seven of the eight outflow sources, tend to be more luminous and associated with higher (C-13)O column density than the rest. Our results suggest that the dense cores are dissipated by the high-velocity molecular outflow in the early stage of star formation. This is consistent with the star formation scenario proposed by Shu et al. (1987).
