Description
The role of low-ℓ orbits is particularly important in determining nuclear properties such as the nuclear radius. This is reflected into mirror energy differences that have been studied systematically in the sd- and fp-shells using existing data as well as new measurements for T=1/2 and T=3/2 mirror nuclei. Low-ℓ orbits contribute differently to mirror energy differences depending on their occupation numbers. Such effect has been explained considering that the addition of a nucleon induces opposite changes in the potential wells of protons and neutrons and that tends to equalize proton and neutron radii [1]. This agrees with recent experimental results [2] and results in a unified description of nuclear charge radii deduced from mirror energy differences and nuclear charge radii measured directly in experiment.
