Inside the nucleus of a deuterium atom

Computer visualization showing the inside the nucleus of a deuterium atom, or "heavy atom"

Computer visualization showing the inside of the nucleus of a deuterium atom, also known as "heavy hydrogen." The deuterium nucleus consists of precisely one proton and one neutron, which are subject to strong quantum effects because of their very tight confinement. The visualization shows some of the resulting wave patterns.
