A previous ASCA observation revealed that the Lyalfpha fluxes of Si and S are significantly higher than those expected from the electron temperature of the bremsstrahlung continuum (Kawasaki et al. 2002). Therefore, it was claimed that the thermal plasma in this SNR is in \"overionization\".　In the XIS spectrum of IC 443, we discovered hump-like features around at 2.7 and 3.5 keV　as well as the strong Lyalpha lines. These humps are well represented by radiative recombination continua (RRC) of H-like Si and S with the electron temperature of approximately 0.6 keV. The ionization temperatures of Si and S determined from the intensity ratios of the RRC to He-like Kalpha line are approximately 1.0 keV and approximately 1.2 keV, respectively. We thus find firm evidence for an extremely-overionized (recombining) plasma. As the origin of the overionization, a thermal conduction scenario argued in the previous work is not favored in our new results. We propose that the highly-ionized gas were made at the initial phase of the SNR evolution in dense regions around a massive progenitor, and the low electron temperature is due to a rapid cooling by an adiabatic expansion.","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Meeting sponsors: The University of Tokyo, The Institute of Physical and Chemical Research, The Japan Society for the Promotion of Science","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064574024","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-09-008E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"理化学研究所"},{"subitem_text_value":"京都大学大学院理学研究科物理学専攻"},{"subitem_text_value":"京都大学大学院理学研究科物理学専攻"},{"subitem_text_value":"理化学研究所"},{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"金沢大学理学部物理学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"RIKEN"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Kyoto University"},{"subitem_text_language":"en","subitem_text_value":"RIKEN"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (ISAS)(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Kanazawa University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山口, 弘悦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小澤, 碧"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小山, 勝二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平賀, 純子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"尾崎, 正伸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"米徳, 大輔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaguchi, Hiroya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ozawa, Midori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Koyama, Katsuji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hiraga, Junko S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ozaki, Masanobu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yonetoku, Daisuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-16"}],"displaytype":"detail","filename":"64574024.pdf","filesize":[{"value":"327.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64574024.pdf","url":"https://jaxa.repo.nii.ac.jp/record/4956/files/64574024.pdf"},"version_id":"a5a84d42-84d1-4f05-a7cb-e55723538fc4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ISM: supernova remnants -
