COMPARISON BETWEEN HARRIS AND WU-ZENG'S FORMULAS FOR ROTATIONAL SPECTRA OF DEFORMED NUCLEI

The abundant data about the high-spin states (up to I^π～30⁺) of ground bands in actinides even-even nuclei,obtained by heavy ion Coulomb excitation,are used to test the various formulas now available for rotational spectra.From the analyses of energy spectra,moments of inertia and γ-transition energies it is found that Wu-Zeng's formula is better than all the rest 2-parameter formulas,including the widely used Harris' formula.In some cases the prediction by Wu-Zeng's formula may be helpful for judging the reliability of some observed data.
