 note = {The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan, We observed the strange X-ray "pulsar" 1E1207.4-5409 using Suzaku and investigated its spectral structures. 1E1207.4-5409 is an X-ray source near the center of the SNR G296.5 + 10.0. Soft X-ray observations by Chandra and XMM-Newton reported "harmonic" absorption structures at about 0.7, 1.4, and 2.1 keV (also might be at around 2.8 keV) in the energy spectrum (Bigmani et al. 2003, Luca et al.2004). The origin of these structures has not clarified yet. If these structures could be due to proton-cyclotron resonance, the magnetic field should be in the range of B approximately 10(exp 14) G, and it would serve as a strong support for the existence of magnetar. Suzaku made observations of this strange source twice and obtained spectral data displaying similar absorption structures at about 0.7, 1.4 and 2.1 keV., Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science, 資料番号: AA0064574080, レポート番号: JAXA-SP-09-008E},
