1.Using a potential model with relativistic correction we evaluated the spectrum, le-pton decay widths and radiative transition widths of heavy quarkonium systems.
13.You can see there's just a really stark contrast in -- in temperature between the surfaces that are -- these radiative cooling found and the roof of the building.
14.A key way to do this is with radiative cooling, a phenomenon that occurs at night when certain materials (like aluminium) radiate enough heat to cool below the ambient temperature of their surroundings.
