alpha-cluster excited states in S-32 are investigated with an extended Si-28 + alpha cluster model, in which the Si-28 core deformation and rotation and the alpha-cluster breaking are incorporated. In the generator coordinate method calculation with the extended Si-28 + alpha cluster model, the alpha-cluster excited states are obtained near the Si-28 + alpha threshold energy. The Si-28 core deformation and rotation effects, and also the alpha-clusters breaking in the Si-28 + alpha system, are discussed. It is found that the rotation of the oblately deformed Si-28 core has a significant effect on the alpha-cluster excited states whereas the alpha-cluster breaking has only a minor effect.
