Some Statistical Problems in the Computation of Nuclidic Mass Formulae
The volume of the literature on nuclidic mass formulae bears witness to much vexation. There is no agreement on the terms to be used. Simple drop-model terms account for the major portion of each mass (v. Weizsäcker 1935) and thus are a natural zeroth approximation. But how may we improve them into a first or second approximation while we are not quite certain about the structure of the nuclear surface? There are also strong shell model terms (discovered experimentally by Duckworth and collaborators, 1950/51), but again we do not yet know a universally acceptable procedure to refine these in higher orders. Anyway, how do we reconcile the collective and the individual particle effects while basic nuclear theory is still unsettled?
