Abstract
To show the existence of precursor phenomena of the transition order → chaos in atomic nuclei a simple analysis has been made, based on a recent criterion proposed by Pavlichenkov. The basic idea is that non-linear effects in rotational bands should lead to bifurcation, which qualitatively changes the spectrum for one of the nuclear excitation branches. Experimental data concerning the isotopes of Er, Hf, Yb, Os, Dy, W strongly support the above criterion. © 1994, Società Italiana di Fisica. All rights reserved.File in questo prodotto:
