초록

We present the results of a highly sensitive (${\sim}10$ mK rms) survey toward the central parts of 22 barred spiral galaxies in $^{12}CO(1-0)$ line using the NRAO 12m telescope at Kitt Peak. Seven of the target galaxies were detected in CO; NGC 3686 has been detected with CO for the first time. We estimated central CO fluxes of $50{\sim}1000\;Jy\;km\;s^{-1}$ and molecular gas masses of $10^7{\sim}10^8\;M_{\odot}$ for those galaxies.
