Fig. 3: Level schemes.
From: Addendum: The observation of vibrating pear-shapes in radon nuclei

These partial level-schemes for 222,224,226Rn show the excited states of interest. Arrows indicate γ-ray transitions. All energies are in keV. Firm assignments of transitions and energy levels in the scheme are from previous work or have been made using γ–γ-coincidence relations; tentatively assigned transitions such as those from the 3− and 5− states in 226Rn are shown as dashed lines. The assignment of spins and parities in brackets are tentative.
