Theoretical descriptions of the first excited state of helium-4 are now consistent with experimental data.
What does the inside of a carbon atom's nucleus look like? A new study provides a comprehensive answer to this question. In the study, the researchers simulated all known energy states of the nucleus. These include the puzzling Hoyle state. If it did not exist, carbon and oxygen would only be present in the universe in tiny traces. Ultimately, we therefore also owe it our own existence.
What does the nucleus of an atom of carbon look like inside? The first comprehensive response to the subject comes from a recent study conducted by Forschungszentrum Jülich, Michigan State University (USA), and the University of Bonn.
A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. This surprised the scientific community; some researchers even believ ...
