Level spin for superdeformed nuclei near<i>A</i>=194

Abstract

Transition energies of 25 superdeformed (SD) bands in 13 nuclei of the A=194 region were fitted by the power-series expansion of I in odd powers of ${\mathit{E}}_{\ensuremath{\gamma}}$/2, \ensuremath{\Elzxh}(I+1/2)=2\ensuremath{\alpha}\ensuremath{\omega}+4/3\ensuremath{\beta}${\mathrm{\ensuremath{\omega}}}^{3}$, where ${\mathit{E}}_{\ensuremath{\gamma}}$/2=\ensuremath{\Elzxh}\ensuremath{\omega}, and by the expression for transition energy, ${\mathit{E}}_{\ensuremath{\gamma}}$=E(I+2)-E(I), where E(I)=AI(I+1) +B[I(I+1)${]}^{2}$+C[I(I+1)${]}^{3}$. Results are generally similar, and level spins for these SD bands are given based on expectations of rotational model behavior.
