The F077400100014 solid angle was 1.3*10**(-4) sr. F077400100015 SAMPLE Two self-supporting titanium foils with the same F077400100016 thickness of 5.1 mg/cm2, one of which was saturated by F077400100017 tritium, were used as targets. Tritium content in the F077400100018 Ti-T irradiated foil was 38.4%. F077400100019 ADD-RES Resonance states with E=3.6+-0.3 MeV and E~11.8 MeV of F077400100020 two neutron system were investigated.
