Last known magic neutron number weakens in heavy elements

An international team of scientists has succeeded to create and detect extremely short-lived atomic nuclei of the element uranium. Having far fewer neutrons than the kind of uranium nuclei found in nature, they exist only for about a millionth of a second. The new data provide key information on how the numbers of neutrons and protons inside exotic heavy nuclei influence their stability. This is important to give better guidance for experiments on the search for new superheavy elements.
