$$alpha$$-decay branching ratio of $$^{180}$$Pt

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.

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.

In a recent international exercise, 10 international nuclear forensics laboratories successfully performed radiochronometry on three low enriched uranium oxide samples, providing 12 analytical results using three different parent-daughter pairs serving as independent chronometers. The vast majority of the results were consistent with one another and consistent with the known processing history of the materials. In general, for these particular samples, mass spectrometry gave more accurate and more precise analytical results than decay counting measurements. In addition, the concordance of the $$^{235}$$U-$$^{231}$$Pa and $$^{234}$$U-$$^{230}$$Th chronometers confirmed the validity of the age dating assumptions, increasing confidence in the resulting conclusions.
