Autoradiography after the discharge experiment showed isotopes with low and high energy radiation components were produced before or during the discharge. The palladium foil after DC glow discharge was analyzed by secondary ion mass spectroscopy which reveal considerably increase in the content of Boron, Nickel. Silicon. sodium (Na), aluminum, calcium, magnesium, manganese, iron, copper and chromium on the surface.\n\nThe controlled out-diffusion method was employed to induce a nuclear reaction in a palladium (Pd) plate with a MnOx film. The time-resolved mass spectra for Pd deuteride revealed tritium (T) production of molecules with mass number 4, which can be D_2, HT or helium during the out-diffusion experiment. Film blackening was observed for most Pd using a normal monochromatic negative photographic film. The radiation from the Pd plate consists of two kinds of components, which may be beta ray and X-ray. Secondary ion mass spectroscopy has shown considerable increase in counts of Li, , sodium (Na), potassium (K) after the out-diffusion experiment. All the results give credence to the suggestion that nuclear reactions possibly occur in the narrow near-surface layer.","subitem_description_type":"Other"}]},"item_28_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"YAMADA, Hiroshi"}]}]},"item_28_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学工学部"}]},"item_28_version_type_27":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山田, 弘"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"kaken11650276.pdf","filesize":[{"value":"3.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kaken11650276.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9662/files/kaken11650276.pdf"},"version_id":"599a22c4-67bb-48b4-b5a3-4210cc851e3e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Autoradiography","subitem_subject_scheme":"Other"},{"subitem_subject":"Deuterium","subitem_subject_scheme":"Other"},{"subitem_subject":"Excess heat","subitem_subject_scheme":"Other"},{"subitem_subject":"Glow discharge","subitem_subject_scheme":"Other"},{"subitem_subject":"Loading of hydrogen","subitem_subject_scheme":"Other"},{"subitem_subject":"Palladium","subitem_subject_scheme":"Other"},{"subitem_subject":"SIMS","subitem_subject_scheme":"Other"},{"subitem_subject":"Transmutation","subitem_subject_scheme":"Other"},{"subitem_subject":"オートラジオグラフィー","subitem_subject_scheme":"Other"},{"subitem_subject":"グロー放電","subitem_subject_scheme":"Other"},{"subitem_subject":"トリチウム","subitem_subject_scheme":"Other"},{"subitem_subject":"パラジウム","subitem_subject_scheme":"Other"},{"subitem_subject":"核変換","subitem_subject_scheme":"Other"},{"subitem_subject":"水素吸蔵","subitem_subject_scheme":"Other"},{"subitem_subject":"真空法","subitem_subject_scheme":"Other"},{"subitem_subject":"過剰熱","subitem_subject_scheme":"Other"},{"subitem_subject":"重水素","subitem_subject_scheme":"Other"}]},"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":"気体中放電による重水素吸蔵金属電極からの過剰熱発生と電極表面生成物に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"気体中放電による重水素吸蔵金属電極からの過剰熱発生と電極表面生成物に関する研究"}]},"item_type_id":"28","owner":"3","path":["1516"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-08"},"publish_date":"2012-02-08","publish_status":"0","recid":"9662","relation_version_is_last":true,"title":["気体中放電による重水素吸蔵金属電極からの過剰熱発生と電極表面生成物に関する研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:00:31.523135+00:00"}
