However, because their cross sections are extremely small, the interactions have not been well studied. One of the photon-photon interactions is Delbrück scattering, in which an incident photon causes a pair creation of an electron and a positron and subsequently they interact with the Coulomb field by an atomic nucleus, leading annihilation. It seems an elastic scattering of a photon. However, there was a critical problem that one cannot derive only the amplitude of Delbrück scattering by the interference with other elastic scattering such as nuclear Tomson scattering and Giant Dipole Resonance. We found theoretically that it is possible to measure selectively the cross section of the Delbrück scattering using linearly polarized laser Compton scattering gamma-ray beams. We have also studied experimentally a possibility of higher-order Delbrück scattering using gamma-ray beams at NewSUBARU.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"基礎科学セミナー","subitem_description_type":"Other"}]},"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":"早川, 岳人"}],"nameIdentifiers":[{"nameIdentifier":"654730","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"早川 岳人","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"654731","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Delbrück scattering using Laser Compton scattering gamma-ray beam","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Delbrück scattering using Laser Compton scattering gamma-ray beam"}]},"item_type_id":"10005","owner":"1","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-12-21"},"publish_date":"2017-12-21","publish_status":"0","recid":"66557","relation_version_is_last":true,"title":["Delbrück scattering using Laser Compton scattering gamma-ray beam"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:47:36.977909+00:00"}
