Abstract(CO)-C-13(1-0)and (CO)-O-18(1-0)emissions in the NGC1333/IRAS6-9 star forming region were mapped with the 13.7 m millimeter wave telescope of Purple Mountain Observatory. The areas covered are 10.3' x 10' for (CO)-C-13(1-0)and 6.8' x 8' for (CO)-O-18(1-0), respectively. Several new compact, molecular cores were discovered and a bipolar outflow of (CO)-C-13(1-0)was identified along the SSV12-IRAS8 direction. We present the observed properties and derived the physical parameters for all the (CO)-C-13(1-0)and (CO)-O-18(1-0)cores. The core distribution and velocity structure are analyzed for this region. The relationship between cores, bipolar outflow and crowded young stellar objects (including infrared sources and HH objects) is also discussed in detail.
