Abstract
- The 6Li(16O,19Ne*)3H multi-nucleon transfer-reaction experiment was performed to populate the highly excited states in 19Ne. The subsequent decay particles, 4He or proton from the 19Ne resonant states, were detected in coincidence with the recoil 3H. The excitation-energy spectra of 19Ne were reconstructed by using the detected proton or 4He and the deduced 18F or 15O, respectively. The broad resonance at about 7.85 MeV (1/2+) was observed with partial decay widths updating the previously reported values, which may have significant impact on the destruction of 18F in astrophysical processes. Several resonances up to very high excitation energies have been identified with large α-clustering strength, which confirm the formation of the cluster structure with one-hole configuration in light nuclei, and encourage further systematic studies of cluster structure in 19Ne.
