The interaction potentials of the He2* excimer, in the a3Σu, b3Πg, c3Σg, and d3Σu electronic states with a ground state helium atom are presented. The symmetry of the interaction potentials closely ...

Improve this page Add a description, image, and links to the helium-atom topic page so that developers can more easily learn about it.

What is an atom? An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter particles called electrons that you can think of as orbiting ...

Almost everything on Earth is made up of atoms, but where do these fundamental building blocks come from?

3He has been inserted into the cavity of an open-cage fullerene derivative close to room temperature, reaching an incorporation fraction of 0.1%. The rate of escape of 3He from this fullerene was ...
