abstracts={The non-axial reflection-asymmetric ¦Â32 shape in some transfermium nuclei with N = 150, namely 246Cm, 248Cf, 250Fm, and 252No are investigated with multidimensional constrained covariant den- sity functional theories. By using the density-dependent point coupling covariant density functional theory with the parameter set DD-PC1 in the particle-hole channel, it is found that, for the ground states of 248Cf and 250Fm, the non-axial octupole deformation parameter ¦Â32 > 0.03 and the energy gain due to the ¦Â32 distortion is larger than 300 keV. In 246Cm and 252No, shallow ¦Â32 minima are found. The occurrence of the non-axial octupole ¦Â32 correlations is mainly from a pair of neutron orbitals [734]9/2 (¦Íj15/2) and [622]5/2 (¦Íg9/2) which are close to the neutron Fermi surface and a pair of proton orbitals [521]3/2 (¦Ðf7/2) and [633]7/2 (¦Ði13/2) which are close to the proton Fermi surface. The dependence of the non-axial octupole effects on the form of energy density functional and on the parameter set is also studied.},
