Abstract

Isotope shift measurements on even-$A$ Pt isotopes have been obtained from $A=186$ to $A=198$. Charge radius differences have been extracted, and are compared to constrained Hartree-Fock plus BCS calculations. A possible shape transition between $^{186}\mathrm{Pt}$ and $^{188}\mathrm{Pt}$ is discussed.
