Recently, a prediction was presented for gamma-ray emission from a cluster of galaxies at a detectable level with modern imaging atmospheric Cherenkov telescopes. The gamma-ray emission was produced via inverse Compton upscattering of cosmic microwave background (CMB) photons by electron-positron pairs generated by collisions of UHE cosmic rays in the cluster. We have observed two clusters of galaxies, Abell 3667 and Abell 4038, searching for very-high-energy gamma-ray emission with the CANGAROO-III atmospheric Cherenkov telescope system in 2006. The analysis showed no significant excess around these clusters, yielding upper limits on the gamma-ray emission. By comparing the upper limit for the north-west radio relic region of Abell 3667 with the model prediction, we can derive a lower limit of the magnetic field of the region of ca. 0.1 microG. This shows the potential of gamma-ray observations in studies of the cluster environment. We also discuss the upper limit from cluster center regions with a model of gamma-ray emission from neutral pion produced in hadronic collisions of cosmic-ray protons with the intra-cluster medium (ICM). The derived upper limit of the cosmic-ray energy density within this framework was one order higher than that of our Galaxy.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"著者人数: 50人","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064306065","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-08-014E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙線研究所"},{"subitem_text_value":"東京大学宇宙線研究所"},{"subitem_text_value":"東京大学宇宙線研究所"},{"subitem_text_value":"山形大学理学部物理学科"},{"subitem_text_value":"茨城県立医療大学"},{"subitem_text_value":"山梨学院大学経営情報学部"},{"subitem_text_value":"東海大学理学部物理学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute for Cosmic Ray Research, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute for Cosmic Ray Research, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Research School of Astronomy and Astrophysics, Australian National University"},{"subitem_text_language":"en","subitem_text_value":"School of Chemistry and Physics, University of Adelaide"},{"subitem_text_language":"en","subitem_text_value":"Narrabri Observatory of the Australia Telescope National Facility, Commonwealth Scientific and Industrial Research Organisation (CSIRO)"},{"subitem_text_language":"en","subitem_text_value":"Institute for Cosmic Ray Research, University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Yamagata University"},{"subitem_text_language":"en","subitem_text_value":"Ibaraki Prefectural University of Health Sciences"},{"subitem_text_language":"en","subitem_text_value":"Faculty of Management Information, Yamanashi Gakuin University"},{"subitem_text_language":"en","subitem_text_value":"Department of Physics, Tokai University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"木内, 隆太"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 正樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"榎本, 良治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"郡司, 修一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"原, 忠生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kiuchi, Ryuta","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Mori, Masaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Bicknell, G.
