<< As Earth rotates along its axis, it wobbles a little bit. This wobbling comes, in part, from how mass is distributed across the planet. Nuclear physics researchers have now observed this same type of wobbling in Au187-a gold isotope that lives for just eight minutes. >>

<< This is the first experimental evidence for longitudinal wobbling bands where the expected signature partner band has also been identified, and establishes this exotic collective mode as a general phenomenon over the nuclear chart. >>
