Title: Structure of 29F in the rotation-aligned coupling scheme of the particle-rotor model

Recent results from RIKEN/RIBF on the low-lying level structure of 29F are interpreted within the Particle-Rotor Model. We show that the experimental data can be understood in the Rotation-aligned Coupling Scheme, with the 5/2 + ground state as the bandhead of a decoupled band. In this picture, the energy of the observed 1/2$$+\atop{1}$$ state correlates strongly with the rotational energy of the core and provides an estimate of the 2 + energy in 28O. Our analysis suggests a moderate deformation, ϵ 2 ~ 0.16, and places the 2 + in 28O at ~ 2.5 MeV.
