Abstract：
Using modified surface delta interaction, the deformed Hartree-Fock calculations for twenty tWo nuclei: ^102—114Ru, ^102—116Pd and ^104—116Cd are performed.Prolate and oblate configurations are obtained. The calculated results show that there exist form transitions and shape coexistence from mass number 102 to 116, and that the single-particle energy spectra are different not only for different mass number but also for different configurations of nuclei. At the same time, it is also found that the numbers of proton and the 3s_1/2 orbit begining to fill with neutrons play important roles in the shape transitions.
