To estimate the excitation cross section, which gives the enrichment factor (final isotope ratio per initial isotope ratio) of the separation method, we devised a method based on a pump-probe MPI procedure. By probing the material remaining after irradiation with the pump pulse, we estimated the cross section of the ground-state transition (6s Rydberg 3;0-0) to be 4.1+/-1.4x10-48 (cm4 s). The enrichment factor predicted from this cross section indicates that a high-performance laser system (20 mJ/pulse, 200 Hz, 10 ns duration) was capable of achieving an enrichment of over 1000-fold in view of the dissociation efficiency under low-pressure gas conditions. Thus, laser separation (elimination) appears to be a promising tool to create positron-emission tomography molecular probes.\n\\n\n--------------------------------------------------------------------------------","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"org/10.1016/j.jms.2012.03004","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-2852","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Wakai, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"478532","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tuchida, Kaduki"}],"nameIdentifiers":[{"nameIdentifier":"478533","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukumura, Toshimitsu"}],"nameIdentifiers":[{"nameIdentifier":"478534","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iida, Hidehiro"}],"nameIdentifiers":[{"nameIdentifier":"478535","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Kazutoshi"}],"nameIdentifiers":[{"nameIdentifier":"478536","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"若井 篤志","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478537","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"土田 一輝","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478538","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"福村 利光","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478539","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"飯田 秀博","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478540","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木 和年","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"478541","nameIdentifierScheme":"WEKO"}]}]},"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":"Determination of two-photon-excitation cross section for molecular isotope separation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Determination of two-photon-excitation cross section for molecular isotope separation"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-03-27"},"publish_date":"2017-03-27","publish_status":"0","recid":"47691","relation_version_is_last":true,"title":["Determination of two-photon-excitation cross section for molecular isotope separation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:36:37.973876+00:00"}
