概要

• 論文の詳細を見る

• We would like to point out that the (K^-, N) reactions are particularly useful for the study of the K-nucleus interaction. We have measured the missing mass spectra derived from the momenta of both neutrons and protons from the ^<12>C (K^-, N) reactions. It was found that an appreciable amount of strength were below the K-nucleus threshold which indicates that the K-nuclear potential is strongly attractive. The missing mass spectra are compared with theoretical calculations. It is found that a potential depth of around -190MeV reproduces well the spectrum of the ^<12>C(K^-, n) reaction and a less deep potential of around -160MeV reproduces well that of the ^<12>C(K^-, p) reaction. Our data show that the K-nucleus potential is very deep to realize kaon condensation in the core of neutron stars.
