Abstract：
The shapes of light Krypton isotopes have been investigated using cranking Woods-Saxon model. The calculated results show that nuclei ^70,72Kr have oblate ground states and coexisting low-lying prolate states, while nuclei ^74,76Kr have prolate ground states and coexisting low-lying oblate states. In addition, the cranking calculations of ⁷²Kr display that the ground-state shape of ⁷²Kr changes from oblate to prolate as ω increases.
