An attempt has been made to study the effect of a nonuniform positive background on the ground‐state energy of a nonmagnetic Wigner lattice. The background is modified with a variable “ripple” parameter in the background charge, represented by a Yukawa‐type charge distribution. Our calculation shows that a Yukawa‐type background leads to a lower ground‐state energy value compared to a Gaussian‐type and constant positive background. © 1993 John Wiley & Sons, Inc.
