Abstract: (APS)
The beta-delayed alpha-particle emission of N16 has been studied, with N16 nuclei produced using 80 MeV/nucleon O18 beams on Be9 targets. The N16 secondary nuclei were mass analyzed and separated from the reaction products using the Michigan State University A1200 isotope separator. A detector array, including four thin surface barrier detectors, a p-i-n diode, a Ge gamma-ray detector, and a two-dimensional position sensitive parallel plate avalanche counter, was used for implantation and study of the separated nuclei. A beta-decay branching ratio of (1.3±0.3)×10−5 to the 1− state at 9.6 MeV and a centroid of 2.35±0.05 MeV for the beta-delayed alpha-particle emission were measured. These results are essential for the analysis of a high sensitivity measurement at Yale University of the low-energy beta-delayed alpha-particle emission of N16, and for understanding the C12(α,γ)16O reaction in the helium burning process in massive stars.- 23.60.+e
