A method to detect and identify 8Be

Angular distributions of protons, deuterons, tritons, alpha particles and 7Li at 7 MeV CM and *Be at IO MeV CM have been measured for the 9Be + 9Be system. The contribution of the compound nucleus mechanism to the reactions under investigation was estimated by an analysis of the light charged particle channels. The 9Be(9Be, 'Be)l0Be angular distribution was compared with the predictions of the DWBA model supplemented with the incoherent compound nucleus contribution. The "Be(Gs) neutron spectroscopic factor deduced from a comparison of theoretical and experimental cross sections at small angles was found to be consistent with the theoretical value given by Cohen and Kurath. NUCLEAR REACTIONS 9Be(9Be,p), 9Be(9Be,d), 9Be(9Be,t), 9Be(9Be,a), 9Be(9Be, 'Li), E(CM)=7 MeV; 9Be(9Be, *Be), E(cM)= IO MeV; statistical model and DWBA analysis.

“…2 The assumption for the semiclassical approximations are even better fulfilled in the case of heavy ions. In order to check the models for another system, we measured the Coulomb breakup of 9 with two rectangular surface-barrier semiconductor detectors in coincidence, 3 whereas the neutrons were detected by a neutron counter consisting of a NE213 liquid scintillator and a XP1040 photomultiplier. For each event, four parameters were recorded on the disk of the data-acquisition computer, viz., the energies of both a particles, their difference in time of flight, and the time difference between one of the a particles and the neutron.…”
