  • Nuclear 'magic numbers' collapse beyond the doubly magic nickel 78

    Scientists from the RIKEN Nishina Center for Accelerator-Based Research and collaborators have used the center's heavy ion accelerator, the RI Beam Factory, to demonstrate that nickel 78, a neutron-rich "doubly magic" isotope of nickel with 28 protons and 50 neutrons, still maintains a spherical sha more

  • Examining puzzling sizes of extremely light calcium isotopes

    Michigan State University researchers have measured for the first time the nuclei of three proton-rich calcium isotopes. One of the most fundamental properties of the nucleus is its size. The nuclear radius generally increases with the number of proton and neutron constituents. However, when examine more

  • Solving a mystery

    Scientists at Tokyo Institute of Technology have extended an existing mathematical model so that it can be used to more accurately predict the products of fission reactions. Nuclear fission is a process by which the nucleus of an atom is split, generally resulting in the formation of two smaller and more

Isotopes of actinium

Isotopes of actinium Actinium (Ac) has no stable isotopes. A standard atomic mass cannot be given. An isotope of actinium occurring within the radioactive disintegration chain of thorium was known as: * mesothorium II : 228Ac The older name ... more
