Abstract

The threshold behavior of photodetachment cross sections involving negative ions of the alkali-metal atoms was investigated. The photodetachment of Li ^- into continuum states was examined in which the excited residual atom was left in both p states [Li(2p_1/2) and Li(3p)], and s states [Li(3s) and Li(4s)]. The dipole polarizabilities of the alkali-metal atoms in the five excited states were found to be very large. The low-energy electron scattering quantities such as phase shifts, elastic cross sections and s wave scattering lengths for electron scattering on excited Li and K atoms were also determined.
