The (d,n) reaction of {sup 7}Be to form the ground state of {sup 8}B was studied for the first time. The reaction was performed with a 25.8 MeV/nucleon beam of {sup 7}Be ions from the A1200 fragment separator at the NSCL. The beam reacted in a CD{sub 2} target in a large scattering chamber. The recoiling {sup 8}B nuclei were observed in a pair of position sensitive detector telescopes covering angles between 2 and 4.5 degrees (lab). A large array of neutron detectors was placed at angles ranging from 175 to 104 degrees ({approximately}0 to {approximately}30 degrees COM) that was able to measure the energy of coincident neutrons by their time-of-flight. The efficiency of the neutron array was measured with a {sup 17}N source also produced in the A1200 separator. The overall response of the detector system was checked by performing the d({sup 12}C,{sup 13}N)n reaction at 22 MeV/nucleon under identical, i.e., low intensity, conditions. The angular distribution of the {sup 8}B singles and the coincident neutrons were measured and will be presented.
