摘要：

We have investigated the F-13(e) resonance states of positronium negative ion below the N = 3 4 and 5 Ps thresholds using highly correlated exponential wave functions Resonance parameters (positions and widths) are extracted employing both the stabilization method and the complex-coordinate rotation method In addition to many Feshbach resonances below the various Ps thresholds we have identified two F-1(e) shape resonances with one each lying above the N = 3 and N = 5 thresholds respectively We have also identified three F-3(e) shape resonances with one lying above the N = 3 threshold and two lying above N = 4 threshold The F-13(e) shape resonances associated with N = 3 Ps threshold and some other Feshbach resonances are reported for the first time in the literature (C) 2010 Elsevier BV All rights reserved
