Abstract：
The three dimensional Total Routhian Surface (TRS) calculations are carried out for 64 nuclei in the 70≤A≤90 region to find triaxial superdeformed nuclei. A total of 12 nuclei are predicted to have triaxial superdeformation in which the neutron rotational energy plays a key role and the neutron shell energy plays additional role in the formation of triaxial superdeformed nuclei.
