Alignment additivity in the two-quasiparticle superdeformed bands ofTl192

Four superdeformed bands have been confirmed in ${}_{}{}^{192}{}_{}{}^{}\mathrm{Tl}$. Two of these bands have ${\mathcal{I}}^{\mathrm{}\left(2\right)\mathrm{}}$ dynamic moments of inertia which are nearly constant with rotational frequency ħω. The other two bands show the characteristic rise of ${\mathcal{I}}^{\mathrm{}\left(2\right)\mathrm{}}$ with increasing ħω seen in most superdeformed bands of the A = 190 region of superdeformation. From comparisons with the odd-A neighbors, it was found that the alignments of these bands relative to a ${}_{}{}^{192}{}_{}{}^{}\mathrm{Hg}$ core can be accounted for from the additive contributions of the assigned quasiproton and quasineutron orbitals. © 1996 The American Physical Society.
