On the existence of ~(1,3)P° resonances in H~- between n = 2 and 3 H thresholds

摘要

We examine the influence of relativistic and QED effects on the existence of the ~(1,3)P° 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° resonances, and fifteen ~3P° resonances. The fifteen ~1P° resonances are classified to be _3(2,0)_n~- (4 ≤ n ≤ 12) and _3(1,1)_n~+ (3 ≤ n ≤ 8). The fifteen ~3P° 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°) series, four Feshbach resonances for _3(1,1)_n~+(~1P°) series, seven Feshbach resonances for _3(2,0)_n~+(~3P°) series, and three Feshbach resonances for _3(1,1)_n~-(~1P°) series.
