Direct correlations between experimental isotope shifts and differentials of spectroscopic and mass observables — •R.Burcu Cakirli^1,2, Klaus Blaum¹, and Richard F.

Empirical correlations in isotopic differentials of charge radii have been combined with the differentials for data on the energy of the first excited 2⁺ state, on R_4/2=E(4₁⁺)/E(2₁⁺), on the transition rate from the 2₁⁺ to the ground state and the two neutron separation energies. These differential results exhibit remarkable consistency with each other although, individually, structure and/or mass observables reveal different patterns. In the past, there are number of valuable studies of isotope shifts comparable to different observables but not the direct correlations as will be presented here. We show that a single general pattern occurs for five different observables for each mass region. This helps one to follow the structural changes more easily by looking at one type of pattern. This study may be a guide for both experimental studies, future measurements in charge radii, masses, spectroscopic observables, and theoretical studies.
