Low-lying levels in F-15 and the shell model potential for drip-line nuclei
MetadataShow full item record
The ground and first excited states in F-15 were studied in resonant elastic scattering using the thick (CH4) gas target method in inverse kinematics with a separated O-14 beam. An analysis of the excitation functions of the elastic scattering was carried out with the potential model. The quantum numbers 1/2(+) (ground state) and 5/2(+) (first excited state) were assigned to the lowest two states in F-15. Also, the widths and the proton decay energies of the unbound levels were obtained. The analysis of the data indicates that a large diffuseness is needed in the Woods-Saxon potential in order to describe single-particle features in drip-line nuclei.
