Abstract

Periodic terms in the nuclear binding energies, such as the pairing energy, are investigated. To this end we introduce a new, general set of mass relations (indicators) sensitive to specific types of periodicities in the binding-energy surface. Based on experimental data, the analysis leads to an improved expression for the (average) pairing term in the mass formulas. No trace of α-clustering is found and an upper limit for the corresponding energy gain can be deduced to be 0.4 MeV per α-particle or 1.5% of the total α-binding energy. The Wigner term, especially important for light nuclei, is accurately determined. An extra binding in odd N = Z nuclei is observed above the average of all other odd-odd nuclei.
