<P> Although the nuclear shell model has existed since the 1960s , the existence of such superheavy , relatively stable nuclides has not been demonstrated . Like the rest of the superheavy elements , the nuclides on the island of stability have never been found in nature , and so must be created artificially in a nuclear reaction to be studied . However , scientists have not found a way to carry out such a reaction . </P>
