The H-dibaryon resonance was sought by a ΛΛ invariant mass spectrum that was obtained by the C12 (K-,K+ΛΛX) reactions. We observed a bump near the ΛΛ threshold, as reported by the previous experiment (KEK E224), with better statistics. Data were c...

1. We have tried to optimize the development condition for the actual size(25*25cm^2) of nuclear emulsion plate. An efficient grain density of -25/100mum was obtained. The darkness of plates, however, shall give a damage for image analysis to reco...

We developed the alpha-ray detector (for natural radio active substance) until 1992. The sensor is P.I.N. photo diode. This device is safely to treat, because it works by connecting a domestic outlet and dry batteries. It costs less than 100,000 y...
