Suppose one attempts to determine the decay constant of a certain physical quantity whose fundamental component decreases exponentially with time. If higher modes are included in the measured values the logarithmic curve of the quantity deviates from a straight line but approaches asymptotically to the latter, which represents the decay of the fundamental mode. The authors introduced an appropriate function which approximated the deviation, and devised a practical method to get the fundamental decay constant. The new method was applied successfully to the neutron population decay experiments, which was carried out with a neutron generator with pulsing function and a graphite stack. The calculatiorial method may apply to any decaying phenomena.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.32.2.299", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Tamagawa, Hajime", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102232", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nishina, Kojiro", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102233", "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": "2020-11-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "32-2-05.pdf", "filesize": [{"value": "828.0 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 828000.0, "url": {"label": "32-2-05.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/30885/files/32-2-05.pdf"}, "version_id": "e55132cc-1393-4364-85bf-776bd0d824b8"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "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": "Determination of fundamental mode decay constant out of a decay curve with higher mode contamination", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Determination of fundamental mode decay constant out of a decay curve with higher mode contamination", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2587"], "permalink_uri": "https://doi.org/10.18999/memfenu.32.2.299", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-11-24"}, "publish_date": "2020-11-24", "publish_status": "0", "recid": "30885", "relation": {}, "relation_version_is_last": true, "title": ["Determination of fundamental mode decay constant out of a decay curve with higher mode contamination"], "weko_shared_id": -1}
