What is the size of the atomic nucleus?

EPJ A Front page
"The similarity renormalization group for three-body interactions in one dimension", selected to illustrate the front cover of the European Physical Journal A in October, 2011. It was also selected by the Editorial Board as the highlighted paper of that month.

	Hardin and Andy Sproles In a paper published in Nature Physics we use America's most powerful supercomputer, Titan, to compute the neutron distribution and related observables of calcium-48. These calculations also impact the size of a neutron star, thereby connecting objects that differ in size by 18 orders of magnitude.
