Excited states in the neutron-rich nucleus 25F

Abstract

The structure of the nucleus 25F was investigated through in-beam γ-ray spectroscopy of the fragmentation of 26Ne and 27,28Na ion beams. Based on the particle-γ and particle-γγ coincidence data, a level scheme was constructed and compared with shell model and coupled-cluster calculations. Some of the observed states were interpreted as quasi single-particle states built on top of the closed-shell nucleus 24O, while the others were described as states arising from coupling of a single proton to the 2+ core excitation of 24O.
