NH3 (1,1) and (2,2) lines were observed simultaneously, and the molecular gas temperature and density are estimated. The NH3 emission is elongated in the smae direction of the entire M-0.13-0.08 cloud and has a large velocity gradient along its major axis. Strong NH3 emission is located in the northern part of the cloud, where a perturbed velocity field and broad line widths are observed. In addition, a new H2O maser spot was detected near one of the nonthermal continuum sources. These observational results suggest the physical association between a part of the M-0.13-0.08 molecular cloud and the nonthermal continuum sources in the Sgr A complex.
