A number of radiogenically produced dysprosium isotopes have been studied by in-source laser spectroscopy at ISOLDE using the Resonance Ionization Laser Ion Source (RILIS). Isotope shifts were measured relative to $$^{152}$$Dy in the $$4f^{10}6s^{2}~^{5}I_{8}$$ (gs) $$rightarrow$$ $$4f^{10}6s6p~(8,1)^{0}_{8}$$ (418.8 nm $$_{rm VAC}$$)resonance transition. The electronic factor, $$F$$, and mass shift factor, M, were extracted and used for determining the changes in mean-squared charge radii for $$^{rm 145m}$$Dy and $$^{rm 147m}$$Dy for the first time.

The $$alpha$$-decay branching ratio of 0.52(5)% from the ground state of $$^{180}$$Pt to the ground state of the daughter nucleus $$^{176}$$Os has been determined more precisely than before. The $$^{180}$$Pt was produced as the $$beta$$-decay granddaughter of $$^{180}$$Hg which was produced and separated with the CERN-ISOLDE facility. The reduced $$alpha$$-decay width calculated with the present result has provided a new picture of the systematics for the $$alpha$$-decay width of neutron-deficient Pt isotopes.

Fine structure in the $$alpha$$ decay of $$^{218}$$At

An $$alpha$$ decay of $$^{218}$$At was studied at the CERN-ISOLDE facility using a laser-ionization technique. Coincidence $$alpha$$-$$gamma$$ data were collected for the first time and a more precise half-life value of T$$_{1/2}$$ = 1.27(6) s was measured. A new $$alpha$$-decay scheme was deduced based on the fine-structure of the $$alpha$$ decay. The results lead to a preferred spin and parity assignment of J$$_{pi}$$ = (3$$^{-}$$) for the ground state of $$^{218}$$At; however, J$$_{pi}$$ = (2)$$^{-}$$ cannot be fully excluded.
