Accurate Calculation of Superdeformed Bands in Hg and Pb

  • The superdeformed (SD) rotational bands in Hg and Pb are analyzed by means of the abc expression for fotational bands:E(I)=a[1+cL(I+1)][1+bI(I+1)-1],which was derived from the Bohr Hamiltonian.The agreement between calculated and observed transition energies is incredibly well.The deviation of the calculated E's from the observed results turns out to be │δ│≤0.5keV (except for a few cases,0.5keV│δ│≤0.75keV).Some transitions which have not been observed yet in these SD bands are also predicted,which may be useful for experimental investigation.

Abstract: The superdeformed (SD) rotational bands in Hg and Pb are analyzed by means of the abc expression for fotational bands:E(I)=a[1+cL(I+1)][1+bI(I+1)-1],which was derived from the Bohr Hamiltonian.The agreement between calculated and observed transition energies is incredibly well.The deviation of the calculated E's from the observed results turns out to be │δ│≤0.5keV (except for a few cases,0.5keV│δ│≤0.75keV).Some transitions which have not been observed yet in these SD bands are also predicted,which may be useful for experimental investigation.
