With the synthesis of heavy elements approaching the super heavy island,the production cross section becomes smaller and the lifetime of the super heavy element becomes longer,which results in the difficulties for identification of the elements by using conventional alpha decay chain technique.
随着合成的超重元素向超重岛逼近,合成截面越来越小,同时,合成的超重元素的寿命可能相对增长,这对利用α衰变链的传统方法鉴别超重元素是非常不利的。
