Vv. Kukhtin et Ov. Shramko, A NEW EVALUATION OF THE ENERGY OF WIGNER BCC AND FCC CRYSTALS, Journal of physics. A, mathematical and general, 26(18), 1993, pp. 963-965
New expressions for energies per site for two Wigner crystals are give
n through Euler-type constants. Numerical values specify those known p
reviously.
