  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+1 state correlates strongly with the rotational energy of the core
and provides an estimate of the 2+ energy in 28O. Our analysis suggest a
moderate deformation, epsilon_2 ~ 0.17, and places the 2+ in 28O at ~ 2.4 MeV.
