Description
The hyperfine structures and isotope shifts of Potassium from N=19 to N=32 (38,39,42,44,46,47−51K) have been measured successfully.
From these spins, magnetic moments and changes in root mean square charge radii 𝛿⟨𝑟2⟩ have been extracted. The model independent spin determinations obtained in this work clarify the level schemes of neutron rich Potassium isotopes. For the first time the range and extend of the 𝜋𝑑3/2 to 𝜋𝑠1/2 ground state inversion has been established. The extracted 𝛿⟨𝑟2⟩, in conjunction with those of Ca, Cr, Mn and Fe provide a first insight into the regional Z dependence of the evolution of
nuclear size beyond 𝑁 = 28.
