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, 104Ru has been proposed as an example
of possible critical-point nuclei with E(5) symmetry.
