AbstractWe present observations of a 4 square degree area toward the Gemini cloud obtained using J = 1-0 transitions of (CO)-C-12, (CO)-C-13, and (CO)-O-18. No (CO)-O-18 emission was detected. This region is composed of 36 core candidates of (CO)-C-13. These core candidates have characteristic diameters of 0.25 pc, excitation temperatures of 7.9 K, line widths of 0.54 km s(-1), and mean masses of 1.4 M-circle dot. They are likely to be starless core candidates or transient structures, which probably disperse after similar to 10(6) years.
