摘要：

We investigate the shape mixing in Se-68 using the adiabatic self-consistent collective method. This nucleus Se-68 is known to show oblate-prolate shape coexistence at low angular momentum. We calculate the collective path between the oblate and prolate minima and show how the collective behaviour of the system changes with angular momentum.
