Abstract: 
The Coriolis decoupling strength in nuclear single-particle (s.p.) states with mixed parity is examined within a reflection-asymmetric deformed shell model. A strong coupling scheme between the parity mixed s.p. state and a coherent quadrupole-octupole vibration mode in the core is considered for odd-mass nuclei. The Coriolis decoupling factor is obtained in a projected form corresponding to good total parity of the system. The average parity of the s.p. state and the decoupling factor are evaluated in several nuclei as functions of the quadrupole and octupole deformation parameters beta(2) and beta(3). It is found that the average s.p. parity obtains various dominant values in the (beta(2), beta(3))-pane. It is shown that by comparing the behaviour of the decoupling factor in the (beta(2), beta(3))-plane to values obtained in a collective quadrupole-octupole model and by requiring consistency between the calculated dominant parity and the experimentally established parity in the ground state one can determine physically reasonable deformation regions for the considered odd-A nuclei.
