The following channels were studied: π++A→π＋＋π-+χ(1); π++A →２π++χ(2); π++A→2π-+χ(3). The data were the first systematic one. As for the differential cross sections, the shape of kinetic energy spectra were compared with each other. As for the integrated cross sections, both their mass number dependence and incident energy dependence were discussed. Furthermore the ratio of integrated cross section of channel(1) to that of channel(2) or (3) were examined. All the features observed were understood qualitatively in the following views: (a) Channel(1) and (2) are mainly contributed by single step reaction; (b) Channel(3) is mainly contributed by multi-step reaction.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_12_description_45":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"1989","subitem_description_type":"Other"}]},"item_12_dissertation_number_47":{"attribute_name":"報告番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第734号"}]},"item_12_relation_37":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"全文はOPACにあり"}],"subitem_relation_type":"hasFormat","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.tulips.tsukuba.ac.jp/opac/volume/607128","subitem_relation_type_select":"URI"}}]},"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":"Tanaka, Manobu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"34883","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2013-12-18"}],"displaytype":"detail","filename":"A0734.pdf","filesize":[{"value":"160.7 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"abstract","url":"https://tsukuba.repo.nii.ac.jp/record/8397/files/A0734.pdf"},"version_id":"58825a60-a66d-4a02-8bdb-4aeba7dd2980"}]},"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":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Pion-induced double pion production on nuclei in the incident momentum range from 0.5 to 1.5 GeV/c","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Pion-induced double pion production on nuclei in the incident momentum range from 0.5 to 1.5 GeV/c","subitem_title_language":"en"}]},"item_type_id":"12","owner":"1","path":["254"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-07-25"},"publish_date":"2007-07-25","publish_status":"0","recid":"8397","relation_version_is_last":true,"title":["Pion-induced double pion production on nuclei in the incident momentum range from 0.5 to 1.5 GeV/c"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-01T07:51:37.910854+00:00"}
