【Abstract】 With the first three terms of Harris formula included and Mottelson’s method followed,a new ralation of the parameters of Bohr-Mottelson rotational spectra formula is brought forward. Superdeformed bands of even-even nuclei and normal deformed bands of nuclei in actinide and rare-earth are fitted with four-parameter Bohr-Mottelson rotational spectra formula.The ralations of the parameters A,B,C,D are studied.The result show,for normal deformed bands,the new relation approach the experiment value in the same degree as the relation deduced from ab formula,but for super-deformed bands,the new relation is closer to the experiment than the relation deduced from ab formula.Three-parameter Harris formula may have better convergence than two-parameter Harris formula.更多还原
