   We propose to observe the middle lobe and the outer lobe of Cen A
   with 2 pointings. Of large area of Cen A outer lobes, we selected 2
   fields, one of which is the middle lobe peak and the other is the
   outer lobe edge. Einstein detected the X-ray excess in the middle
   lobe regions, while ROSAT discovered the arc-shaped, rim-brightening
   X-ray excess from the N edge of the outer lobe. So, we want to
   determine the origins of these X-ray excesses by analyzing the X-ray
   spectra of both regions. At the same time, it is also expected to
   detect the inverse-Compton X-rays scattering off the CMB photons from
   the outer lobe itself. By comparing the inverse-Compton X-rays flux
   and the synchrotron radio flux, we can determine the magnetic field
   strength in the outer lobe without any assumptions.
