The H-4 resonance was investigated in the transfer reactions H-2(t,p)H-4 and H-3(t,d)H-4 using cryogenic liquid targets of deuterium and tritium and 58 MeV triton beam. The multidetector system with a large angular acceptance was used to measure the recoil protons and deuterons in coincidences with tritons or neutrons from the decay of H-4. Data analysis involved careful considerations made for the competing processes of final state interaction and quasifree scattering. The experimental data show a peak with resonance parameters E-res = 3.05 +/- 0.19 MeV and Gamma(obs) = 4.18 +/- 1.02 MeV. The pole of S-matrix corresponding to the physical values of energy and width, E-0 = 1.99 +/- 0.37 MeV and Gamma(0) = 2.85 +/- 10.3 MeV, has been extracted. (C) 2004 Elsevier B.V.
