Triple shape coexistence and shape evolution in the N=58 Sr and Zr isotopes

The triple shape coexistence specific for the 0(+) states and the evolution of the shape coexistence and mixing in the neutron-rich N = 58 Sr and Zr isotopes are studied within the complex excited VAMPIR approach using a realistic effective interaction based on the Bonn A potential in a large model space. The influence of the shape mixing on the structure and dynamics of the positive-parity states up to spin 20(+) in Sr-96 and Zr-98 is discussed and comparison to the available data is presented.
