Abstract：
Using modified surface delta interaction, the deformed Hartree-Fock calculations for twenty two nuclei such as ^102—114Ru, ^102—116Pd, ^104—116Cd etc. are performed in the gds and gdsh configuration space, respectively. Prolate and oblate configurations are obtained. It is shown that there exist shape transitions for the nuclei with the mass number from 102 to 116, the resultant single-particle energy spectrum is changed not only with the mass number but also with the configuration, and the results, by considering the 1h _11/2orbit, are quite different from those obtained in the gds configuration space. Moreover, the number of protons in the nucleus and filling up the 1h _11/2orbit, especially with neutrons, play important roles in the single-particle energy spectrum and the shape transition.
