Finite nuclear size effects play an increasingly important role in precision atomic and nuclear physics. For example, they have been found to strongly affect the determination of the V_ud matrix element of the CKM matrix (arXiv:2309.16893)
Determining the absolute charge radius of some short-lived nucleus entails careful assembly of several pieces spanning different fields.
Measurements...
Once measurements have been converted into nuclear radii data, the challenge remains to combine these measurements into a consistent set of radii. Given the high number of radii (>800) to optimize and the tight coupling of radii from relative measurements, care must be taken to make a completely accurate non-linear approach feasible. radbase, an open-source set of Python codes, analyzes the...
Databases, web tools and applications developed at the Nuclear Data Section will be presented.
