Abstract

The complex angular momentum (CAM) calculated low-energy 0 < E < 5 eV electron elastic total cross section (TCS) for In is benchmarked through its recently measured electron affinity (Walter et al, Phys. Rev. A 82, 032507 (2010)). The TCSs for Tl and Ga atoms are then calculated using the CAM method. From the dramatically sharp resonances in the TCSs binding energies for Tl^- and Ga^- negative ions formed during the collisions are extracted and compared with existing values. Three stable bound negative ions of Tl are predicted.
