We report on a more precise bα for the 180Pt ground state (g.s.)
The bα values for several platinum isotopes were deduced by comparing measured α-decay intensities to expected production yields, based on similar heavy-ion reactions studied in the rare-earth region
Summary
Alpha decay is a useful probe for studying the underlying structures of nuclei involved in the process. Reduced α-decay widths (δα2) are sensitive to the overlap in wave function between the initial and final states connected by the decay [1] These may be calculated, for instance, using the Rasmussen approach [2], which requires experimental α-decay energies and partial half-lives. The bα values for several platinum isotopes were deduced by comparing measured α-decay intensities to expected production yields, based on similar heavy-ion reactions studied in the rare-earth region. Due to this approach, the extracted value of bα (180Pt) ≈ 0.3% had a large uncertainty factor of 3–5 [5]
