UT-ORNL Study: Calcium-48’s ‘Neutron Skin’ Thinner Than Previously Thought

An international team led by joint UT-Oak Ridge National Laboratory faculty used America’s most powerful supercomputer, Titan, to calculate the neutron distribution and related observables of calcium-48, an isotope with an atomic nucleus consisting of twenty protons and twenty-eight neutrons. Computing the nucleus revealed that the difference between the radii of neutron and proton distributions—called

UT-ORNL Study: Nano-trapped Molecules Potentially Key to Advanced Storage Devices

Single atoms or molecules imprisoned by laser light in a doughnut-shaped metal cage could unlock the key to advanced storage devices, computers and high-resolution instruments, according to a recent UT-ORNL study. In a paper published in Physical Review A, a team composed of Ali Passian of Oak Ridge National Laboratory, and Marouane Salhi and George
