Radiocarbon is produced by the galactic cosmic rays, which are modulated by the solar wind and the interplanetary magnetic field in the heliosphere. The production rate of radiocarbon, therefore, reflects the state of solar magnetic activity. Most distinct index of solar magnetic activity it the group sunspot number. The variations of sunspot number have shown clear cyclicity since the 18^\u003cth\u003e century with average length being about eleven years. The sunspots, however, have once almost disappeared during the period of 1645-1715 AD due to extraordinary weakening of solar activity. This period has been called as the Maunder Minimum. There is no remarkable cyclicity in the sunspot variations. We, therefore, investigated the cyclicity of radiocarbon content in tree rings from the Maunder Minimum in order to clarify the characteristics of solar activity during this period. We compared two radiocarbon records obtained newly by our group and by Stuiver et al. The results of frequency analyses have shown that solar magnetic reversals had maintained through the Maunder Minimum and that the length of the \"eleven-year\" cycle was stretched to 13-15 years.", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "第17回名古屋大学タンデトロン加速器質量分析計シンポジウム平成16(2004)年度報告 Proceedings of the 17th symposiumon Researches Using the Tandetron AMS System at Nagoya University in 2004\\\n日時:平成17 (2005)年1月24日(月)､25日(火) 会場:名古屋大学シンポジオン Date:January 24th and 25th, 2005 Place:Nagoya University Symposion Hall", "subitem_description_type": "Other"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/sumrua.16.57", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学年代測定資料研究センター"}]}, "item_9_relation_43": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110007150933/", "subitem_relation_type_select": "URI"}}]}, "item_9_rights_12": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "名古屋大学年代測定資料研究センター"}, {"subitem_rights": "本文データは学協会の許諾に基づきCiNiiから複製したものである"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "宮原, ひろ子"}], "nameIdentifiers": [{"nameIdentifier": "81827", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Miyahara, Hiroko"}], "nameIdentifiers": [{"nameIdentifier": "81828", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "毛受, 弘彰"}], "nameIdentifiers": [{"nameIdentifier": "81829", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Menjo, Hiroaki"}], "nameIdentifiers": [{"nameIdentifier": "81830", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "桑名, 宏輔"}], "nameIdentifiers": [{"nameIdentifier": "81831", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Kuwana, Kousuke"}], "nameIdentifiers": [{"nameIdentifier": "81832", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "増田, 公明"}], "nameIdentifiers": [{"nameIdentifier": "81833", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Masuda, Kimiaki"}], "nameIdentifiers": [{"nameIdentifier": "81834", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "村木, 綏"}], "nameIdentifiers": [{"nameIdentifier": "81835", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Muraki, Yasushi"}], "nameIdentifiers": [{"nameIdentifier": "81836", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "中村, 俊夫"}], "nameIdentifiers": [{"nameIdentifier": "81837", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakamura, Toshio"}], "nameIdentifiers": [{"nameIdentifier": "81838", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00005461793.pdf", "filesize": [{"value": "530.4 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 530400.0, "url": {"label": "KJ00005461793.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/11748/files/KJ00005461793.pdf"}, "version_id": "5c2c16d2-6cfa-4c2b-8947-9e3790b5a732"}]}, "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": "樹木年輪中^\u003c14\u003eCで探るマウンダー極小期の太陽活動変動(第17回名古屋大学タンデトロン加速器質量分析計シンポジウム平成16(2004)年度報告)", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "樹木年輪中^\u003c14\u003eCで探るマウンダー極小期の太陽活動変動(第17回名古屋大学タンデトロン加速器質量分析計シンポジウム平成16(2004)年度報告)"}]}, "item_type_id": "9", "owner": "1", "path": ["1245"], "permalink_uri": "https://doi.org/10.18999/sumrua.16.57", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-06-04"}, "publish_date": "2010-06-04", "publish_status": "0", "recid": "11748", "relation": {}, "relation_version_is_last": true, "title": ["樹木年輪中^\u003c14\u003eCで探るマウンダー極小期の太陽活動変動(第17回名古屋大学タンデトロン加速器質量分析計シンポジウム平成16(2004)年度報告)"], "weko_shared_id": null}
