摘　　要：Based on the B-spline basis method, the properties of the helium atom confined inside an endohedral environment,such as buckminster fullerene, are studied. In our calculations, the endohedral environment is a parabolic potential well. In this situation, the phenomenon of 'mirror collapse' is exhibited for energy levels of a confined helium atom. The 'giant resonance' of oscillator strength of the dipole transition emerges with the variation of depth of the confining well. The physical mechanisms of these phenomena are analyzed in this paper.Based on the B-spline basis method, the properties of the helium atom confined inside an endohedral environment,such as buckminster fullerene, are studied.
