All those shapes are symmetrical vertically and horizontally. Physicists want to find asymmetrical nuclei because some theories predict that such deformed nuclei could exhibit strange new physical properties. Experiments over the last few decades have hinted that certain arrangements of protons and neutrons result in a pear-shaped nucleus, narrow on one side and bulging on the other.
For the new study,

, physicist Peter Butler of the University of Liverpool in England and an international team probed two potentially pear-shaped nuclei: radon-220,

, which is made up of 86 protons and 134 neutrons, and radium-224,

, with its 88 protons and 136 neutrons. Scientists can determine the shape of nuclei by measuring the pattern of radiation they emit.
At the On-Line Isotope Mass Separator facility at CERN outside Geneva,

, Butler’s team fired protons at a thick slab of uranium carbide. The high-energy protons shattered the atoms in the block,

, including radon-220 and radium-224. The physicists filtered out the isotopes they wanted and stripped away the atoms’ electrons,

, leaving behind a stockpile of nuclei. Then the researchers used magnets to accelerate the nuclei to nearly 10 percent of the speed of light toward a thin layer of metal foil. The nuclei interacted with stationary atoms in the foil as they passed through, resulting in the emission of a measurable stream of gamma radiation.
The radiation measurements confirmed that both radon-220 and radium-224 nuclei have an asymmetric pear shape. The radium appears to maintain a rigid pear shape, while the radon is shiftier: Its mass continuously jiggles around so that the fat and narrow ends trade places.
