摘要： By making use of the method of few-body physics,the energy spectra of low-lying states of a three-electron spherical dot have been calculated. The quantum-size effects on the energy spectra of three electrons are shown.The res ults show that the orders of energy levels do not change when quantum dot diamet ers change.As a result, the energies of the states of L=3k?(k=1,2,…)ful filling π (-1)L=1 are lower than those of their adjacent states.

The quantum-size effects on the energy spectra of three electrons are shown.The res ults show that the orders of energy levels do not change when quantum dot diamet ers change. As a result, the energies of the states of L=3k (k=1,2,…) fulfilling $\pi$ (-1)L=1 are lower than those of their adjacent states.
