Outline of Final Research Achievements |
Aiming at K-atom and Ξ-atom spectroscopy by transition edge sensor (TES), we performed stepwise experiments at J-PARC while proceeding with the development of a new TES with collaborators of NIST. (1) The first exotic-atom experiment "Precision spectroscopy of K-3He / 4He atom X-rays with TES (J-PARC E62)" was conducted successfully. (2) Ξ-atom experiment is granted to be the next experiment, but we are still waiting for beam time due to troubles in J-PARC. (3) Hard X-ray TES development for future experiments was carried out by trial manufacture and performance test, and sufficient performance was obtained for 17.5 keV X-ray.

Academic Significance and Societal Importance of the Research Achievements |
我々は、従来より一桁以上良い分解能をもつX線検出器TESを世界に先駆けハドロン物理研究に導入し、J-PARCの大強度ビームと組み合わせることで、他の追随を許さない研究を展開した。新たな手法を確立し、エキゾチック原子を用いた強い相互作用の研究に革新をもたらした点で大変意義深い。さらに、将来に向けた新たな硬X線用TESの開発も行い、原子核中のK-・Ξ-のポテンシャルを定量的に明らかにする系統的実験に向け、低エネルギーQCDと中性子星の構造研究の研究の飛躍的進展が期待できる。
