Abstract
Experimental data on the angular momentum dependence of parity splitting of yrast bands in different nuclei are analyzed using a one-dimensional model of octupole motion with axial symmetry. A two parameter formula, based on a solution of the Schrödinger equation with a double-minimum potential, predicts that the parity splitting exponentially decreases with I(I+1) and gives a good fit to these data. Moreover, it relates the observed parity splitting directly to the internal barrier height of the potential.
