A previous calculation of energy bands in lithium which employed the orthogonalized plane wave method, was extended with the determination of the energies of states along the STA100!, STAll0!, and STAlll! axes in the Brillouin zone. The Fermi energy was also determined. The Fermi surface predicted by these calculations is not in contact with the Brillouin zone, and is only slightly distorted from the sphere characteristic of free electrons. (auth)
