摘要：

High-precision results are presented for calculations of the nonrelativistic energies, relativistic corrections, and quantum electrodynamic corrections for the 2 (2)S, 2 (2)P, and 3 (2)S states of Li and Be(+), using nonrelativistic wave functions expressed in Hylleraas coordinates. Bethe logarithms are obtained for the states of Be(+). Finite mass corrections are calculated with sufficient accuracy to extract the nuclear charge radius from measurements of the isotope shift for the 2 (2)S-2 (2)P and 2 (2)S-3 (2)S transitions. The calculated ionization potential for Be(+) is 146 882.923 +/- 0.005 cm(-1).
