The experimental data of CO depletion measured by Watanabe et al. (2003, ApJ, 588, L121) was analyzed, and obtained the diffusion constant of DH = 1.6 x 10(exp -4) ML(sup 2) s(sup -1) in H2O + CO ice at the temperature of 15 K, where ML stands for monolayers. It is suggested that the dominant mechanism of hydrogen atoms at 15 K is quantum tunneling by estimating the activation energy of diffusion.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046650065","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宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名古屋大学 大学院環境学研究科"},{"subitem_text_value":"名古屋大学 大学院環境学研究科"},{"subitem_text_value":"名古屋大学 大学院環境学研究科"},{"subitem_text_value":"Cairo University Dept. of Astronomy, Faculty of Science"},{"subitem_text_value":"Cairo University Dept. of Astronomy, Faculty of Science"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Environmental Studies"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Environmental Studies"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University Graduate School of Environmental Studies"},{"subitem_text_language":"en","subitem_text_value":"Cairo University Department of Astronomy, Faculty of Science"},{"subitem_text_language":"en","subitem_text_value":"Cairo University Department of Astronomy, Faculty of Science"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木村, 友香"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"千貝, 健"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 哲生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Shalabiea, O.
