A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is ...

An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium ...

"Our measurement can be used in different ways", says Julian Krauth, first author of the study: "The radius of the helium nucleus is an important touchstone for nuclear physics." Atomic nuclei are ...

After an intricate game of particle jockeying, physicists have now measured the radius of the helium nucleus five times more precisely than before. Why do that? Well, atomic physicist Julian ...

In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium is the best atomic system ... applied to determine the radius of helium nuclei.

The atomic structure of this muonic helium ion ... The measured charge radius of helium will serve as an ideal test case for such calculations. If agreement is obtained, it should then be possible ...

Traditionally, nuclear radii are determined using ... been successfully applied to the lightest atomic nuclei, such as hydrogen and deuterium. For helium, highly precise measurements also exist ...
