We performed high-resolution observations of a Galactic Center 50-km s$^{-1}$ molecular cloud in the CS $J$= 1–0 line using the Nobeyama Millimeter Array (NMA). The molecular cloud mainly has three different spatial components with large velocity widths of up to 60 kms$^{-1}$. The northwest component is located at an apparent contact point to the Sgr A east shell, and elongated along the boundary ...
