Physicists Discover Bubbles in Atomic Nucleus

By wochit 25 October 2016

Scientists have found bubbles in a medium very different from these oxygen bubbles — an atomic nucleus. The researchers found that silicon-34 has a “bubble nucleus” with few protons in its center. BUBBLING UP Scientists have found the first experimental evidence that an atomic nucleus can harbor bubbles. The unstable isotope silicon-34 has a bubblelike center with a paucity of protons, scientists report October 24 in Nature Physics. This unusual “bubble nucleus” could help scientists understand how heavy elements are born in the universe, and help scientists find new, ultraheavy stable isotopes.
