Radii of nuclear charge distributions carry information about the strong and electromagnetic forces acting inside atomic nucleus. Whereas global behavior radii is governed by bulk properties matter, their local trends are affected quantum motion proton neutron constituents. The measured differential $\ensuremath{\delta}\ensuremath{\langle}{r}_{c}^{2}\ensuremath{\rangle}$ between numbers $N=28$ ...

The ∆I = 1 "staggering" effect is investigated in the energy spectrum of positive and negative parities yrast band even-even actinide nuclei. described by formula proportional to discrete approximation fourth-order derivative function ∆E(I). It shown that characterized "zigzag" behavior does not vanish within observed range angular momenta.
