R-matrixcalculations of the electron collisions with a lithium atom at energies below the 3s excitation threshold are presented. The 1Se, 3Se, and 1Po phase shifts calculated in the near-threshold energy range are in excellent agreement with previous theoretical studies. The threshold behavior of the 3Po phase shift is accurately analyzed along with the resonance located at the scattering energy ∼60 meV. The phase shifts and cross sections calculated here show two resonances below the 3s threshold that have not been previously reported.
