Structure of 29F in the Rotation-aligned Coupling Scheme of the Particle-Rotor Model
Abstract
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, epsilon2 ~ 0.17, and places the 2+ in 28O at ~ 2.4 MeV.
