Marble model atom

WebA study published in the journal 'nature' measuring the shape of the nucleus of a Radium-224 (Ra-224) atom. The result is strange; the nucleus is not shaped like a European football (sphere) or even an American football (ellipsoid). The 88 protons and 136 neutrons are packed into the shape of a pear, sporting a big bulge on one end.
