What it covers
A study of how the I=1/2 states change structure between ¹⁸¹Tl and the lighter gold isotopes ¹⁷⁷,¹⁷⁹Au.
Methods and setup
Laser spectroscopy and complementary nuclear data on thallium and gold beams, published in Physics Letters B. The observables are isotope shifts and hyperfine structure that track deformation and configuration change.
Why it matters
Gold and thallium sit next to the mercury shape-coexistence region. A change in the I=1/2 configuration is the spectroscopic signature that the same shape-driving physics is crossing Z=80.
