Coriolis Interaction Between Three Nilsson Bands in Pa

By comparing new experimental results with calculations, it is shown that the levels above the ½ ${}_{}{}^{-}{}_{}{}^{}[5,$ 3, 0] ground-state band in ${}_{}{}^{233}{}_{}{}^{}\mathrm{Pa}$ and ${}_{}{}^{231}{}_{}{}^{}\mathrm{Pa}$ may be interpreted as resulting from the ${\mathrm{½}}^{+}$[6, 6, 0], the ${\frac{3}{2}}^{+}\mathrm{}[6,5,1]\mathrm{}$, and the ${\frac{5}{2}}^{+}\mathrm{}[6,4,2]\mathrm{}$ bands involved in a three-band Coriolis interaction.
