S-wave resonances in positron scattering from Li and Na

摘要：

We have calculated S-wave resonances in the e+-Li and e+-Na systems using the stabilization method in the framework of hyperspherical coordinates. We have located all the previously known S-wave resonances predicted by Ho 1,2 and observed relatively good agreement for the resonance positions. In addition, the resonances associated with the Ps (n=2) threshold for the e+-Na and e+-Li systems are reported for the first time.
