ROTATIONAL STATES OF EVEN–EVEN NUCLEI

Abstract

Rotational energy levels of axially asymmetric nuclei have been calculated in the manner of Davydov and Filippov, and a comparison with experiment shows good quantitative agreement. It is suggested that agreement may be improved by introducing the Bohr–Mottelson vibration–rotation interaction and a centrifugal stretching correction analogous to the type used in molecular spectra. The D–F method seems to be particularly useful for nuclei in the transition regions between "rotational" and "near-harmonic" modes of collective excitation.
