Abstract. Recent measurements of the cross sections for the diffractive breakup of 11 Be on a light ( 12 C) target have been reported. These data cover a fraction of the final-state three-body phase space and cuts on these data exhibit resonant structures in the neutron-10 Be continuum. These breakup data provide a motivation to test the coupled discretised continuum channels method in the context of the spectroscopy of continuum states in 11 Be and similar neutron-rich systems near the dripline.

An experiment to measure the 18 F(p,α) 15 O cross section at low centre of mass energies has been performed with the TRIUMF-UK Detector Array (TUDA) facility at TRIUMF. Measurements of the 18 F(p,α) 15 O reaction rate at four separate centre of mass energies; 665 keV, 430 keV, 330 keV and 250 keV, were carried out. The main goal of the experiment was the measurement of the 18 F(p,α) 15 O cross section between 250 keV and 300 keV to help constrain the contribution to the reaction rate from nearby states and determine the effect of interference on the overall 18 F(p,α) 15 O reaction rate from the proposed low lying 3/2 + states with the higher 664.7 keV 3/2 + state. A high intensity 18 F beam (∼5x10 6 pps) was used to bombard a 31.6±1.9 µg.cm −2 polyethylene target within the TUDA scattering chamber at the four centre of mass energies. Four highly segmented silicon strip detector arrays were used for coincident detection of the reaction products. Preliminary results will be presented.10th Symposium on Nuclei in the Cosmos
