Abstract

It is shown that a new way of applying a set of nuclear-mass relations among neighbouring nuclei, known as the Garvey–Kelson (GK) relations, holds exceptionally well for all currently measured masses. It is then demonstrated that these relationships are not adequately fulfilled for the best-known procedures to predict unknown masses. This suggests that these models may be optimized by constraining them to satisfy the (generalized) GK equations.
