The radio complex Sgr B region is observed with the X-Ray Imaging Spectrometers ( XIS ) on board Suzaku .
This region exhibits diffuse iron lines at 6.4 , 6.7 and 6.9 keV , which are K \alpha lines of Fe \emissiontype I ( neutral iron ) , Fe \emissiontype XXV ( He-like iron ) and Fe \emissiontype XXVI ( H-like iron ) , respectively .
The high energy resolving power of the XIS provides the separate maps of the K-shell transition lines from Fe \emissiontype I ( 6.4 keV ) and Fe \emissiontype XXV ( 6.7 keV ) .
Although the 6.7 keV line is smoothly distributed over the Sgr B region , a local excess is found near at ( l,b ) = ( \timeform { 0 D .61 } , \timeform { 0 D .01 } ) , possibly a new SNR .
The plasma temperature is kT \sim 3 keV and the age is estimated to be around several \times 10 ^ { 3 } years .
The 6.4 keV image is clumpy with local excesses nearby Sgr B2 and at ( l,b ) = ( \timeform { 0 D .74 } , - \timeform { 0 D .09 } ) .
Like Sgr B2 , this excess may be another candidate of an X-ray reflection nebula ( XRN ) .
