摘要：

Convergent renormalized perturbation series in powers of the electron-electron interaction are proposed for calculating the energy of a quantum dot. The method is illustrated by calculating the ground and several excited states of a quantum dot consisting of two electrons. Comparison between the present results and those of an exact numerical integration shows the great accuracy of the proposed method over the whole range of the electron-electron coupling constant values.
