The present work extends the previous work^[2] on 5-ion system to consider 7-ion system （i.e., Au^47＋ -Au^53＋）.

It is found that more highly charged ions, e.g., Au^53＋, Au^54＋ etc., could be able to be neglected, however, less highly charged ions, e.g., Au^47＋, Au^46＋ etc., are rather important. Therefore, a new idea to consider 8-ion system, i.e., Au^46＋ - Au^53＋, is under way. As a supplement, we discuss the simultaneous reaction, which would be important in this sort of works.展开更多
