and $^{192,193} $ Re nuclei were measured for the first time. The uncertainty of previously
known masses of $^{189,190} $ W and $^{195} $ Os nuclei was improved. Observed
irregularities on the smooth two-neutron separation energies for Hf and W isotopes are
linked to the collectivity phenomena in the corresponding nuclei.
