VARIATION OF THE INNER ELECTRONIC CLOUD IN A 2-ELECTRON ATOMIC SYSTEM

The variation of the inner electronic cloud of a two-electron system when the outer electron is moving far away or coming close is investigated in this paper mainly by analyzing the shape-density. The geometric character and features of internal motion of the 1S(e) helium states having different K-numbers have been shown, the mechanism for energy transfer and the details of radial-raddial correlation have been inspected. The motion of the inner electronic cloud as a whole is found to be strongly correlated with the motion of the outer electron.
