"STAGGERING" EFFECT IN EVEN-EVEN NUCLEI WITH QUADRUPOLE AND OCTUPOLE DEFORMATIONS

The ΔI = 1 “staggering” effect is investigated in the energy spectrum of positive and negative parities of the yrast band of eveneven actinide nuclei. The “staggering” effect is described by the formula proportional to the discrete approximation of the fourthorder derivative of the function ΔE(I). It is shown that the “staggering” effect is characterized by the “zigzag” behavior and does not vanish within the observed range of angular momenta.
