It is found that both fluxes are proportional to the photon emission rate and that the proportionality factor depends rather weakly on the plasma parameters in the ranges of practical interest. This implies that the observed emission line intensity can be a good measure of the ionization flux or the recombination flux. The relation between the total radiation power rate and the ionization or recombination flux is also considered. For a hydrogen plasma in ionization balance the Balmer-alpha line intensity takes the maximum value near the optimum temperature of 1.3 eV, while for plasmas out of ionization balance it takes the minimum near that temperature. This latter characteristic corresponds to the recently observed \"inverse edge-localized mode\" in divertor plasmas. For neutral hydrogen and ionized helium, it is found that in the recombining plasma of low electron temperature, T_e, and density, n_e, the radiation energy close to the ionization potential of the ground state is emitted during one recombination event. In the ionizing plasma of high Te and low n_e, a similar amount of energy is emitted during one ionization event. Emission line intensities of hydrogen and helium were measured in the Large Helical Device, and the time variation of n_e at the initial and final phases of a discharge was estimated. The results agreed well with the interferometer measurement, and this indicated that the variation of n_e was dominated by their ionization or recombination processes rather than by diffusion. The total radiation energy of hydrogen and helium in the recombining phase was found to be less than 1% of the stored energy of the plasma.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Institute of Physics"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1063/1.1507588","subitem_relation_type_select":"DOI"}}]},"item_2_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher version"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1063/1.1507588","subitem_relation_type_select":"DOI"}}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"?2002 American Institute of Physics."}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Goto,  Motoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sawada,  Keiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"FUJIMOTO,  Takashi","creatorNameLang":"en"}],"familyNames":[{}],"givenNames":[{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-03-23"}],"displaytype":"detail","filename":"2536 PhysPlasmas_9_4316.pdf","filesize":[{"value":"214.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"2536 PhysPlasmas_9_4316.pdf","url":"https://nifs-repository.repo.nii.ac.jp/record/541/files/2536 PhysPlasmas_9_4316.pdf"},"version_id":"5503a6c9-07d2-4efd-b24b-fcc4976c3586"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"hydrogen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"helium","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ionisation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ion recombination","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plasma diagnostics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spectral line intensity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"plasma collision processes","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Relations between the ionization or recombination flux and the emission radiation for hydrogen and helium in plasma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relations between the ionization or recombination flux and the emission radiation for hydrogen and helium in plasma","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["7"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-08"},"publish_date":"2009-12-08","publish_status":"0","recid":"541","relation_version_is_last":true,"title":["Relations between the ionization or recombination flux and the emission radiation for hydrogen and helium in plasma"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-10-05T05:59:59.873152+00:00"}
