Abstract
We study a system composed of N identical charged bosons confined in a harm onic trap. Upper- and lower-energy bounds are given. It is shown in the lar ge-N limit that the ground-state energy is determined within an accuracy of +/-8% and that the mean-field theory provides a reasonable result with a r elative error of less than 16% for the binding energy.
