Abstract:The Be-7 fragments produced in one-proton removal from relativistic B-8 nuclei of 936 MeV/nucleon in a carbon target have been detected in coincidence with gamma rays emitted by these fragments at the reaction target. It is found that 13 ± 3% of the Be-7 fragments are released in the 429 keV excited state, Be-7*, which gives direct experimental information on the ground state configuration of B-8. The longitudinal momentum distributions (p||) of the Be-7 fragments have been measured, both inclusively and in coincidence with de-excitation γ-rays from Be-7*. The widths and cross sections of the respective p|| distributions are compared with calculations in a three-body cluster model.
