Observation of these cometary ions is based on the identification of a specific feature in the phase space distribution of ions (ion-pickup shell), We found that the pickup shell is usually filled only partially (∿50%). This observation suggests that the efficiency of the energy diffusion is comparable to that of the pitch angle diffusion. From the spatial asymmetry in the cometary ion density observed between inbound and outbound parts of the spacecraft orbit, it is suggested that there was a difference of a factor of 2-3 between the ion production rates around the inbound and outbound orbit.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166815000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"京都大学理学部"},{"subitem_text_value":"電波研究所"},{"subitem_text_value":"東海大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"寺沢, 敏夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向井, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 亘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北山, 正信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平尾, 邦雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TERASAWA, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUKAI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAKE, W.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KITAYAMA, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIRAO, K.","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":"2020-01-24"}],"displaytype":"detail","filename":"SA0166815.pdf","filesize":[{"value":"499.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166815.pdf","url":"https://jaxa.repo.nii.ac.jp/record/32986/files/SA0166815.pdf"},"version_id":"8f042c71-0744-4b83-9214-1451559c88d4"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"太陽風内のハレー彗星起源イオンの空間分布 : 「すいせい」による観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"太陽風内のハレー彗星起源イオンの空間分布 : 「すいせい」による観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"32986","relation_version_is_last":true,"title":["太陽風内のハレー彗星起源イオンの空間分布 : 「すいせい」による観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:49.001798+00:00"}
