Nuclear Sizes and the Isotope Shift
Darwin-Foldy nuclear-size corrections in electronic atoms and nuclear radii are discussed from the nuclear-physics perspective. Interpretation of precise isotope-shift measurements is formalism dependent, and care must be exercised in interpreting these results and those obtained from relativistic electron scattering from nuclei. We strongly advocate that the entire nuclear-charge operator be u...

متن کاملNuclear sizes and ground states
1 Nuclear dimensions 2 Nuclear size may be probed with scattering experiments, such as Rutherford's bombardment of a gold foil with alpha-particles which established the nuclear model of the atom, or electron scattering. Bombarding particles must have de Broglie wavelengths (given by p = h= ̧) smaller than the nuclear size of a few fm to actually probe the nuclear structure; this requires p ̧ 10¡...
متن کاملIsotope Shift in Mg I
The lines of the Mg I spectrum, lying in the visible and in the photographic infrared regions, have been examined and some of them found to show structure. It is pointed out that the structure should be attributed to isotope shift, which, in the case of the 3s3p 'P —3s3d 'D series, owes its origin to the fact-that the smd 'D terms, perturbed by the p''D term, have passed on to this term some of...
متن کاملMany-Body Calculations of the Isotope Shift
Atomic energy levels are commonly evaluated assuming that the nuclear mass is infinite. In this report, we consider corrections to atomic levels associated with finite nuclear mass. These corrections are referred to as isotope shifts. We evaluate isotope shifts using many-body perturbation theory (MBPT), following the pioneering work by Mårtensson-Pendrill et al. [1, 2, 3, 4, 5, 6, 7, 8, 9]. We...
