... and helium, Starace's group applied HHG theory to heavier (and more rare) gaseous atoms having many electrons – elements such as xenon, argon and krypton. They discovered that the process would ...

... have 55 protons and 78 neutrons in the nucleus, by using optical methods to observe the effect when atomic electrons are excited to higher energy levels. The Berkeley researchers designed their own ...
