摘要：

We calculate the S-3(e) and S-1(e) scattering lengths in low-energy e(-) + Rb(Ss), Cs(Gs), and Fr(7s) collisions. Our approach is based on the relativistic version of the modified effective range theory (MERT) and extrapolates eigenphases provided by Dirac R-matrix calculations to zero energy. To test the accuracy of our MERT extrapolation method, we compare the fine-structure components for the lowest P-3(o) resonance of Fr- ion with full Dirac R-matrix calculations.
