The technique, explained in a peer-reviewed paper published in Annalen der Physik, works for both the matter and the charge radii.
In contrast, the microscopic models conventionally used by nuclear physicists are complex and fail to identify which results follow inherently from fundamental principles. The area is topical because experiments over the last few decades to measure nuclear sizes, often using major particle accelerators internationally, have built up an ever more detailed body of data.
