Sequences of threshold resonances, a consideration of the threshold splitting. T. T. Gien Department of Physics, Memorial University of Newfoundland, St. John's, Newfoundland, Canada A1B 3X7 Sequences of S, P, D Feshbach resonances were located below the n=2 H threshold. The positions and widths of the 1Po(1) and 1Po(2) resonances agree well with experimental data. A tentative simple consideration of the threshold splitting in our calculation enables the relocation of the third singlet 1Po(3) at a position that agrees with the one determined by Lindroth et al recently.
