  Highly accurate nonrelativistic ground-state wave function and energy of the
lithium atom is obtained in the Hylleraas basis set. The leading relativistic
corrections,as represented by Breit-Pauli Hamiltonian, are obtained in fair
agreement with the former results. The calculational method is based on the
analytical evaluation of Hylleraas integrals with the help of recursion
relations.
