    Nuclear isomers in superheavy elements as step** stones towards the island of stability

    The stability of an atomic nucleus is determined by the outcome of a tug-of-war between the attractive strong nuclear force and the repulsive electrostatic force between the protons in the nucleus. If 100 prot...
