Abstract

Based on results from a measurement of weak decay branches observed following the β^- decay of ⁹⁴Y and on lifetime data from a study of ⁹⁴Zr by inelastic neutron scattering, collective structure is deduced in the closed-subshell nucleus ⁹⁴Zr. These results establish shape coexistence in ⁹⁴Zr. The role of subshells for nuclear collectivity is suggested to be important.
