摘要：

We report on results from Suzaku broadband X-ray observations of the Galactic supernova, remnant (SNR) RX J1713.7-3946 with an energy coverage of 0.4-40 keV. With a sensitive hard X-ray measurement from the HXD PIN on board Suzaku, we determine the hard X-ray spectrum in the 12-40 keV range to be described by a power law with photon index Gamma = 3.2 +/- 0.2, significantly steeper than the soft X-ray index of Gamma = 2.4 +/- 0.05 measured previously with ASCA and other missions. We find that a simple power law fails to describe the full spectral range of 0.4-40 keV and instead a cutoff power law with bard index Gamma = 1.96 +/- 0.05 and high energy cutoff epsilon(c) = 9 +/- 1 keV provides an excellerit fit over the full bandpass.
