摘要

The analysis of shape evolution between spherical U(5) and gamma-soft O(6) in Ru isotopes, based on the constrained Hartree-Fock-Bogoliubov (HFB) method with the Skyrme force SLy4 has been carried out. By examining potential energy curves (PECs) of even-even Ru isotopes with 50 <= N <= 66, Ru-104 has been proposed as an example of possible critical-point nuclei with E(5) symmetry.
