| Abstract: | We examine the influence of relativistic and QED effects on the existence of the 1,3P o H- resonances between n = 2 and 3 hydrogen thresholds, the relativistic and QED corrections and the coupling effects between the high singlet and triplet states are considered as first-order perturbations. We firstly obtain accurate non-relativistic resonant energies and widths of fifteen 1P o resonances, and fifteen 3P o resonances. The fifteen 1P o resonances are classified to be 3 (2, 0) - n ( 4 ? n ? 12) and 3 (1, 1) + n ( 3 ? n ? 8). The fifteen 3P o resonances are classified to be 3 (2, 0) + n ( 3 ? n ? 12) and 3 (1, 1) - n ( 4 ? n ? 8). We found there exist six Feshbach resonances for 3 (2, 0) - n (1P o ) series, four Feshbach resonances for 3 (1, 1) + n (1P o ) series, seven Feshbach resonances for 3 (2, 0) + n (3P o ) series, and three Feshbach resonances for 3 (1, 1) - n (1P o ) series.
