It is shown that these changes can be explained by assuming that magnetospheric ions have been decelerated by the parallel potential drop by which electrons have been accelerated. It has also been found that frequencies of \"no ion observation events\" in the inverted-V regions are statistically correlated with the electorn acceleration energy. These results support the theory that the inverted-V electron acce leration is caused by the parallel potential drop. Comparison of the auroral electron precipitation patterns observed on several consecutive orbits has revealed that an inverted-V event becomes splitted into many discrete bands which expand both equatorward (into the diffuse precipitation region) and poleward (into the polar cap). These phenomena are observed mostly during geomagnetically quiet periods immediately following the recovery phase of substorms.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0166845000","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":"神戸大学工学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"北山, 正信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小原, 隆博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向井, 利典"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西田, 篤弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"賀谷, 信幸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KITAYAMA, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"OBARA, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUKAI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NISHIDA, A.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAYA, N.","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":"SA0166845.pdf","filesize":[{"value":"626.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0166845.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33006/files/SA0166845.pdf"},"version_id":"febc74e3-22ea-43f8-8952-cc8b73b5cdee"}]},"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":"EXOS-C ESP による Inverted-V 型電子降下の観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"EXOS-C ESP による Inverted-V 型電子降下の観測"}]},"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":"33006","relation_version_is_last":true,"title":["EXOS-C ESP による Inverted-V 型電子降下の観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:18:18.453560+00:00"}
