Description

The use of constant-N contours in the (ω, λ) plane is demonstrated both for establishing diabolical points and for studying regularities and fluctuations in the spectrum of single-particle states. Likewise the average properties and fluctuations of empirical proton-neutron interactions, obtained from double differentials of the total energy with respect of N and Z, are discussed for the ground states of all even-even nuclei with N>40 and as a function of the rotational frequency for the lowest even-spin, positive-parity decay sequence of deformed rare earth nuclei.
