Study of A = 100–150 superdeformed mass region by using two-parameter formula

Özet

Empirical formulae of rotational spectra consisting two parameters, such as single-term energy formula,E = aJb for spin J , and ab formula, were used to study the different features of superdeformed band in A = 100–150mass region nuclei. The nuclear kinematic and dynamic moment of inertia for the ground-state rotational bands werecalculated for this purpose and both showed gradual rise with rotational frequency. The study of ΔI = 2 staggeringeffects in the -ray energies, where the two sequences J = 4i; 4i + 1 and J = 4i + 2, (i = 0; 1; : : :) are bifurcated,was also done. We also calculated the variation of the gamma ray energies from a smooth reference using the fourthderivative of the gamma ray energies at a given spin. The excellent agreement between the observed and calculatedtransition energies are in good support of the two-parameter formula.
