Abstract. Based on our previous works about the configuration-constrained potential-energy-surface model investigating multi-quasiparticle high-K states, we have further developed the cranking configuration-constrained total Routhian surface method to calculate the collective rotations of the multi-quasiparticle high-K states. The non-axial deformed Woods-Saxon potential has been adopted to obtain single-particle levels. The Woods-Saxon potential gives excellent single-particle level spacing, which is very important for the excitation energy calculations of high-K states. In order to improve pairing calculations, a particle-number-conserving pairing method has been incorporated into the TRS calculation. The calculated moments of inertia can well reproduce experimental values. The structures of the high-K states can be analyzed by the calculations.
