However, as FT density per unit area rises, it becomes difficult to count the number of tracks because tracks overlap one another and are unable to be readily distinguished. The atomic force microscope (AFM) has a potential to observe fission tracks with high density after a short time etching.　This research developed sample preparation techniques (e.g., polishing and etching) for AFM observation, established equipment settings for image capturing, and applied to date practical samples. The results were satisfactory, though the sample as old as 1 Ga is the oldest limit to be dated because the weak etching prevents extraction of FT from other structures. High resolution of AFM enables observation of possible alpha recoil tracks in zircon.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:24654173, 研究期間(年度):2012-04-01 - 2015-03-31","subitem_description_type":"Other"},{"subitem_description":"出典：「原子間力顕微鏡を利用した放射線損傷年代測定法の開発」研究成果報告書　課題番号24654173\n（KAKEN：科学研究費助成事業データベース（国立情報学研究所）） \n（https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24654173/24654173seika/)を加工して作成","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学環日本海域環境研究センター","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052300","subitem_identifier_reg_type":"JaLC"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=60272944"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=60272944","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24654173/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-24654173/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24654173/24654173seika/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-24654173/24654173seika/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-28"}],"displaytype":"detail","filename":"OC-PR-HASEBE-N-kaken 2015-4p.pdf","filesize":[{"value":"124.6 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"OC-PR-HASEBE-N-kaken 2015-4p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/45966/files/OC-PR-HASEBE-N-kaken 2015-4p.pdf"},"version_id":"a8ae121b-7240-4767-ac76-2adafbbde991"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"原子間力顕微鏡を利用した放射線損傷年代測定法の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"原子間力顕微鏡を利用した放射線損傷年代測定法の開発"},{"subitem_title":"Development of radiation damage dating by AFM","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2819"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-10-01"},"publish_date":"2018-10-01","publish_status":"0","recid":"45966","relation_version_is_last":true,"title":["原子間力顕微鏡を利用した放射線損傷年代測定法の開発"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T09:36:16.522085+00:00"}
